docs: upgrade docs dependencies for Astro 6 (#3908)

* chore(deps): upgrade docs dependencies for Astro 6 (DOCSDEV-60)

- astro 5.x -> 6.x, starlight 0.37 -> 0.38, markdown-remark 6.x -> 7.x
- docs-design-system 0.11 -> 0.12, starlight-versions 0.6 -> 0.8
- starlight-links-validator 0.19 -> 0.23, mermaid 11.12 -> 11.14
- Migrate i18n collection to use i18nLoader (Astro 6 requirement)
- Pass explicit sidebar options to starlightFullViewMode for Zod compat

* chore(deps): bump remaining docs devDependencies

Address review: @eslint/js and eslint bumped from 9.x to 10.x (docs
package only; root ESLint 8.x unchanged). Also patch/minor bumps for
astro, @astrojs/markdown-remark, prettier, spectaql, @typescript-eslint/parser,
typescript-eslint, astro-eslint-parser, eslint-plugin-astro, globals.

* chore(deps): pnpm dedupe

Removes ~256 duplicate packages from the lockfile. Lockfile only;
no package.json specs changed.

* Revert "chore(deps): pnpm dedupe"

This reverts commit 04b2f6d.
