[refactor] retire legacy docs/ current tree and clean up dead hooks (#3645)

Dev docs migrated to the docs-next plugin and the legacy plugin runs
with includeCurrentVersion: false, so docs/ and i18n/zh-CN/.../current/
were no longer being compiled. Remove the source trees plus all the CI /
governance / i18n hooks that still referenced them.

Deletions:
- docs/ (1504 files), i18n/zh-CN/docusaurus-plugin-content-docs/current/
(1518 files), and current.json
- sidebars.ts (legacy plugin sidebar; unused under
includeCurrentVersion: false)
- .github/workflows/check-legacy-docs-frozen.yml (legacy-only gate)
- crowdin.yml (dead config; no workflow invokes Crowdin and target
i18n/ja does not exist)
- tools/maintainers.json + tools/check_review.py +
.github/workflows/approve-check.yml (dormant maintainer-approval gate;
the workflow was entirely commented out)

Updates:
- docusaurus.config.js: drop sidebarPath for the legacy plugin
- .github/workflows/build-check.yml: drop dead docs/* / zh-current /
sidebars.ts case branches
- .github/workflows/manual-i18n-translate-workflow.yaml: default
source_dir docs -> docs-next
- .docs-governance/rules.yml + owners.yml: drop 'current' version, the
docs / zh-current content roots, related doc_type / sync_policy entries,
and legacy paths in each owner block
- scripts/docs-governance/{manifest,lint-i18n-sync}.js: drop legacy
current branches from path resolution; STRONG_SYNC_VERSIONS no longer
includes 'current'
- local_build_docs.sh: stop populating legacy current dirs; only the
versioned_docs reimport remains
