src/essential-dev/README.md:20

• This section is still out of sync with the feature manifest after the GitLens removal. The manifest now installs the0807.git-graph-plus and does not include the GitHub PR/Actions extensions listed here, so the README will still tell users they get extensions that are not actually installed.
