Description

chore: Update stale issues GitHub action to use the latest version.

NOTE: Pointing to explicit tag or commit enables to avoid any breaking changes, specially when the repository is maintained by 3rd party. Since aws-actions is maintained by us, to avoid changing the GitHub action reference every time new version is released, it was discussed to set it to main.

Motivation and Context

Stale Issue GitHub action was failing in some repositories due to missing stale PR message. The GitHub action was fixed to handle the scenario where PR were considered as issues by GitHub API.

Testing

Local testing using instructions provided at https://github.com/aws-actions/stale-issue-cleanup/.
