Open issue when ADMX/L builds fail (#754)

ADMX/L build failures are sometimes hard to spot and this isn't great.
Opening an issue and syncing it to Jira will help us to notice those
failures and to start handling them.

Example of issue opened by the action: #756. (It was opened before
fixing the job order and without the Jira tag to avoid cluttering Jira
with test issues)
