This release note somehow was having the exact same UUID as the one
for repo_server repo [1] which resulted in reno never being copied
to the integrated repo and published.
While we can re-generate UUID and promote it, it's been over 6 years
since feature implementations, and updating UUID will result in reno
renderring for the current release. Thus it's more logical to delete it
reather then fix it.
