updating sync-task-issues action

Stream: general

[Rob Lewis]

You may have noticed CI errors related to "API limit exceeded." Our current hypothesis is that this is due to the dependent-issues action behaving inefficiently when a PR is merged and it needs to update blocked-by-other-PR tags.

The sync-task-issues action, which checks off dependencies in a PR message once they're merged, does almost the same thing but more efficiently. It should be fairly easy to modify the script to also add/remove labels when appropriate.

Is anyone interested in trying to do this? We could run a fork of this action, but if polished enough, I suspect the sync-task-issues maintainer might be interested in a PR.
