[BUGFIX] Bump phpdocumentor/guides-* to fix bignums-tip leak in tabs (#1243)

## Summary

Bumps phpdocumentor monorepo subsplit packages so the `bignums-tip` text
leak in tabs (#1236) is fixed:

- `phpdocumentor/guides` 1.9.6 → 1.10.1
- `phpdocumentor/guides-restructured-text` 1.9.6 → 1.10.1
- `phpdocumentor/guides-theme-bootstrap` 1.9.6 → 1.9.7
- `phpdocumentor/filesystem` 1.9.0 → 1.10.0

Resolves #1236.

## Why this fixes #1236

The `bignums-tip` rst-class leak inside tabs was caused by a
dual-storage bug in `phpDocumentor\Guides\Bootstrap\Nodes\TabsNode`: tab
children were kept in two parallel arrays (a private `$tabs` cache plus
the `$value` array inherited from `CompoundNode`). The
`ClassNodeTransformer` correctly removed orphan `ClassNode`s from
`$value`, but the bootstrap-theme Twig template iterated the stale
`$tabs` cache, which still referenced the pre-transform tab and emitted
its `ClassNode`'s value (`bignums-tip`) as plain text.

The fix landed incidentally via [phpDocumentor/guides#1316 /
1bdb18c7](phpDocumentor/guides@1bdb18c7),
which moved the Tabs/Tab directives out of `guides-theme-bootstrap` into
`guides-restructured-text`. The Bootstrap classes are now deprecation
shims that delegate to `RestructuredText\Nodes\TabsNode`, whose
`getTabs()` is derived from `getChildren()` — no stale cache, no leak.

## Why this couldn't be merged earlier

`guides-theme-bootstrap:1.9.7` declared
`phpdocumentor/guides-restructured-text:^1.10 || ^2.0`, but no `1.10.x`
of `guides-restructured-text` had been published on Packagist yet — the
constraint was unresolvable for any consumer with the default
`minimum-stability: stable`. I filed
[phpDocumentor/guides#1341](phpDocumentor/guides#1341);
@jaapio tagged `1.10.1` on 2026-05-05 and the release is now
installable.

## Test plan

- [x] `composer update phpdocumentor/*` resolves cleanly with the
existing constraints in `composer.json` (no constraint changes needed)
- [x] `make test-integration` — 114 tests, 1140 assertions, OK (1 new
test added)
- [x] `make test-unit` — 83 tests, 183 assertions, OK
- [x] `make test-xml` — all `guides.xml` fixtures validate
- [x] `make test-docs` — project docs render successfully
- [x] `make test-rendertest` — render test corpus renders successfully
(incl. ru_RU, fr_FR, de_DE localizations)
- [x] `make phpstan` — `[OK] No errors`
- [x] Reproducer from #1236 rendered against upgraded packages —
produces `<ol class="bignums-tip">` with no literal text leak
- [x] Same reproducer rendered against pre-upgrade packages — still
leaks `bignums-tip` (regression test would catch it)

## New regression fixture

`tests/Integration/tests/bignum/bignum-in-tabs/` — mirrors the
reproducer from #1236 (rst-class sibling to a list inside a `tabs::`
directive) and asserts the rendered tab pane contains `<ol
class="bignums-tip">` without leaking the literal class name as text.
The fixture lives under `bignum/` rather than `tabs/` because the
existing `tabs/` test harness already has a top-level `input/` directory
and the data provider only recurses into directories without one.

## Downstream PHPStan fix included


[phpDocumentor/guides#1316](phpDocumentor/guides#1316)
made `phpDocumentor\Guides\Bootstrap\Nodes\AbstractTabNode` a
`class_alias()` shim. The local
`T3Docs\Typo3DocsTheme\Nodes\GroupTabNode` extends that class, and
PHPStan can't follow runtime aliases — so the bump initially caused two
`Quality` job failures (`return.type` and `staticMethod.notFound`).

Fix is a one-line import switch to the new home:
`phpDocumentor\Guides\RestructuredText\Nodes\AbstractTabNode`. Runtime
behaviour is identical (the alias makes the inheritance chain the same
either way), and the deprecation notice the shim would otherwise emit on
file load is silenced as a side effect.

`1.9.6...1.10.1` (with risk assessment and pointers for deeper review)
is in the [comment thread
below](#1243 (comment)).

## Notes for review

- No `composer.json` constraint changes were required — the existing
`^1.9.4` / `^1.9` / `^1.7` constraints all resolve to the new versions.
The only code change is the one-line `GroupTabNode` import switch
documented above.
- The bump pulls in `phpdocumentor/guides:1.10.1` (a minor) — the
changes between 1.9.6 and 1.10.1 are dominated by the Tabs/Tab move
(#1316) plus deprecation shims; full integration suite passes without
changes to any other expected fixtures.
