CI Updates

[pyrox0]

This PR does 2 things:

• A pr-manager action that checks FCP dates, notifies the mappings team if a PR is done in FCP, and also ensures all needed labels are assigned to a PR.
• Updates the javascript dependencies of the update-base and diff-uploader actions. This also solves some warnings that appear under running those actions.

Taking this out of FCP since there's some improvements I need to make to it.

Closing per what I said in the quilt mappings discord thread, someone else can pick this up if they want.
