Automatically Remove Issues from Triage Board When Closed

[aj-stein-nist]

User Story:

As a NIST OSCAL developer, in order to improve efficiency and reduce impact on developer bandwidth to perform ongoing triage of issues, I would like to have improved automation to remove the card from the Issue Triage board once its issue has been closed as complete.

Goals:

This had been discussed internally with Dave and the NIST OSCAL dev team. This work is a continuation of #1209. We now automatically bring in issues to the triage board, it is now time to balance this out and make sure they get removed.

Dependencies:

@david-waltermire-nist I did look through the backlog and did not find this issue created previously, but we talked about it enough. PRs incoming after some more testing when I unify the two two jobs into one workflow file.
