Identify pull requests that mention a closed issue, and potentially
re-trigger the UAT cycle. If all issues referenced in the UAT comment of a
linked PR are closed (and it is not already running the QCPR workflow), rerun
the QCPR workflow (qcthat.yaml) if available.
Usage
TriggerUAT(
intClosedIssue = GuessIssueNumber(),
strOwner = GetGHOwner(),
strRepo = GetGHRepo(),
strGHToken = gh::gh_token()
)
