chore(deps): reinstall @backstage/plugin-api-docs to fix node-gyp errors in tree-sitter

Regenerated `yarn.lock` by running:

- `yarn install`
- `cd packages/app`
- `yarn remove @backstage/plugin-api-docs`
- `yarn add @backstage/[email protected]` (same version reinstalled)

This picked up transitive dependency updates that resolve `node-gyp` build
errors in `tree-sitter`
