CI: publish the MSI as a Forgejo release on tags

On a v* tag the msi job creates the release (if missing) and attaches the
MSI under its own name and as SQLInsight-Pro-x64.msi, so the newest can be
fetched without login from releases/latest/download/. The artifact upload
stays for ordinary pushes. Uses the Actions token, or RELEASE_TOKEN if set.
