Restore only publishing docs on release (#982)

* ci: revert doc publishing workflow changes from #980

Restore the doc publishing workflow that was removed in PR #980:
- Restore docs-sync.yml for daily auto-generated docs
- Restore doc generation steps in release.yml after package publish
- Restore NPM_TOKEN environment variable

* ci: restore doc generation on release only

Restore doc generation steps in release.yml that run after package
publish. Remove the daily docs-sync.yml workflow - docs should only
be regenerated when we release.
