[CI] Fix driver update script with IGC (#16647)

A couple of things changed that cause the script to break:
1. The `.sum` file in the `compute-runtime` release no longer lists IGC
debs.
2. The format of the IGC tags changed

Update the script to find the IGC tag using a regex in the
`compute-runtime` release description, which is the only place that
lists the corresponding IGC version.
