Use of "Release-As:" in commit

### TL;DR

Per [the docs](https://github.com/googleapis/release-please?tab=readme-ov-file#how-do-i-change-the-version-number), previously I could force a version by adding `Release-As: 0.2.0` somewhere in the body of the commit message used in the squash-merge to main regardless of other content in the message. Now it seems to only work if `Release-As: 0.2.0` is not accompanied by other Github things like co-authors or perhaps just any presence of `---` in the commit message.

### Expected behavior

The GHA workflow run would create/update the release-please PR with the version provided in the `Release-As:` line.

### Observed behavior

It does not set the provided version.

### Action YAML
