autorelease: Fix rolling-release version for a release (#40522)

Because PHP's `version_compare()` is used for the comparison, something like `6.0.0+rolling.12345.gbeef` < `6.0.0-alpha+rolling.12345.gbeef`. To avoid this being a problem, if the version number isn't already -alpha then bump it as for a point release, e.g. `6.0.0` → `6.0.1-alpha`.
