chore(ci): replace closed-issue-message action with powertools action

[dreamorosi]

Issue number: closes #5636

Summary

Changes

Please provide a summary of what's being changed

This PR updates the workflow that runs when an issue is closed to use an action from our own shared repository (aws-powertools/actions) rather than a 3rd party one.

The new action uses the gh CLI to perform the action rather than a custom script.
