What is this PR about? Usually we don't merge release branches into main, we would lose the release branch and any commit in this branch should already be in main, was this open by mistake?

To add new commits to this release, it should be done through patch releases, as described here: https://dev.docs.pyansys.com/how-to/releasing.html#new-releases
