Serialize post-mlinter-review after post-link to avoid PR description race (#47832)
* Serialize post-mlinter-review after post-link to avoid PR description race
Both jobs patch the PR description; running them in parallel causes the
last writer to silently overwrite the other's changes. Adding
`needs: post-link` ensures post-mlinter-review reads the already-updated
description (with CI badge) before appending the mlinter state block.

* Add always() so post-mlinter-review runs even if post-link fails
