[BUG] PR Automation mislabels breaking change as VersionReviewRequired

### API Spec link

https://github.com/Azure/azure-rest-api-specs/pull/38517

### API Spec version

NA

### Describe the bug

The breaking change PR checks should apply the BreakingChangeReviewRequired label when the PR makes breaking changes in the same API version. The VersioningReviewRequired label is appropriate when the PR makes changes to an existing API version that would not be breaking if made in a new API version.

This is not working correctly in some cases, as illustrated in PR #38517.

The [Swagger BreakingChange check](https://github.com/Azure/azure-rest-api-specs/actions/runs/18939286077) finds that enum values have been removed -- a breaking change

but applied the VersioningReviewRequired label rather than the BreakingChangeReviewRequired label.

### Expected behavior

The breaking change PR checks should apply the BreakingChangeReviewRequired label when the PR makes breaking changes in the same API version. The VersioningReviewRequired label is appropriate when the PR makes changes to an existing API version that would not be breaking if made in a new API version.

### Actual behavior

See description.

### Reproduction Steps

See the linked PR check report.
