Bug: Verify dependencies workflow not working in main branch

[phipag]

Summary

The verify dependencies workflow fails when merging a PR to main.

Error: Both a base ref and head ref must be provided, either via the `base_ref`/`head_ref` config options, `base-ref`/`head-ref` workflow action options, or by running a `pull_request`/`pull_request_target`/`merge_group` workflow.

Example: https://github.com/aws-powertools/powertools-lambda-java/actions/runs/15777946106/job/44476531450
