Revert @vitest/eslint-plugin 1.6.21 bump

[gtbuchanan]

Problem

main went red at the Build (lint:eslint) step after #241 bumped @vitest/eslint-plugin 1.6.20 → 1.6.21. That release's "Chai-style expect chains" change (upstream #920) regressed vitest/valid-expect to flag expect.any(...) as an "unknown modifier" (upstream #924), so the pre-existing expect.any(String) assertion in packages/vitest-config/test/configure.test.ts fails --max-warnings=0.

It surfaced on main (not on #241's own PR) because #248's source merge invalidated turbo's task cache, forcing vitest-config#lint:eslint to actually re-run against 1.6.21 rather than replay a pre-1.6.21 cache entry.

Fix

• Revert the catalog to the last-good 1.6.20 (mature; lint passes). The test code is correct — expect.any is a valid matcher — so no test change.
• Add a repo-local Renovate rule to skip 1.6.21, so Renovate advances straight to the fixed 1.6.22 (#925) once it clears the 3-day minimumReleaseAge quarantine, instead of re-applying the broken release. The rule is scoped to .github/renovate.json (not the shared preset) and documents the removal condition.

Root-only change (catalog + lockfile + renovate config), so no changeset is required (same as #241).
