Include review request issue URLs in the license review comment

dash-licenses logs the URL of each review request (IP Lab GitLab issue)
it creates, but these URLs are not part of the -summary CSV. Capture the
tool output to a log file and parse the 'A review request was created /
already exists <url>' lines, associating each URL with its dependency.
The PR comment now links each unvetted dependency to its review request
issue, and falls back to guidance when no request could be created.
