Labeler workflow do not trigger changelog-check workflow.

[kaovilai]

What steps did you take and what happened:

Velero labeler currently use GITHUB_TOKEN and do not trigger changelog-check to rerun which requires PR to either have another commit/push or require close/open of PRs to pass changelog check.

We need to add either a Personal Access Token or GitHub App installation access token to the following workflow to solve. https://github.com/vmware-tanzu/velero/blob/4dfbacd2a1738701824b40a92e37c7bf291c93fa/.github/workflows/auto_label_prs.yml

If you do want to trigger a workflow from within a workflow run, you can use a GitHub App installation access token or a personal access token instead of GITHUB_TOKEN to trigger events that require a token. ref

What did you expect to happen:

The following information will help us better understand what's going on:

If you are using velero v1.7.0+:
Please use velero debug --backup <backupname> --restore <restorename> to generate the support bundle, and attach to this issue, more options please refer to velero debug --help

If you are using earlier versions:
Please provide the output of the following commands (Pasting long output into a GitHub gist or other pastebin is fine.)

• kubectl logs deployment/velero -n velero
• velero backup describe <backupname> or kubectl get backup/<backupname> -n velero -o yaml
• velero backup logs <backupname>
• velero restore describe <restorename> or kubectl get restore/<restorename> -n velero -o yaml
• velero restore logs <restorename>

Anything else you would like to add:

Environment:

• Velero version (use velero version):
• Velero features (use velero client config get features):
• Kubernetes version (use kubectl version):
• Kubernetes installer & version:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):

Alternative is to merge the changelog check into labeler workflow and use conditions to gate if changelog check should be passing.
