Release notes for the v14.0.0-rc.2 release

Editor assessment

Release notes for the v14.0.0-rc.2 release is a complete subject for a release artifact: the reader knows exactly what the commit contains and why it exists, including the pre-release channel from the version string. The docs type fits the changelog file, the missing scope is conventional for release notes, and no body is needed. Hygiene is clean. A correct, publishable example. The rc identifier is fully stated, which is the complete content a pre-release notes commit requires of its subject.
