Tooling-only prep for the upcoming docs version cut. Snapshots will land
in a follow-up PR.
- Finish the developer_portal -> developer_docs rename: update package.json
scripts, manage-versions.mjs usage strings, DocVersionBadge plugin id list
(replaces bogus 'tutorials' and 'developer_portal' ids with the real
'default', 'components', 'admin_docs', 'developer_docs'), DocVersionBanner
dead branch, DOCS_CLAUDE.md, README.md
- Add admin_docs version add/remove scripts (which previously didn't exist)
- Generalize fixVersionedImports in manage-versions.mjs to walk every
section's snapshot dir with a depth-aware regex, and skip fenced code
blocks; replaces the previous hard-coded two-file list
- Remove orphan files: developer_portal_versions.json, tutorials_versions.json
(no such plugin), and the empty docs/components/versions.json and
docs/developer_docs/versions.json that were accidentally tracked inside
content directories
- Exclude auto-generated sidebar.js and sidebar.ts from the ASF license check
(these are produced by docs/scripts/convert-api-sidebar.mjs from the
OpenAPI spec, and a future version cut would otherwise commit them)
