v1.3.7.2: Fix Auto-Updater & GLIBC Mismatch

Hey everyone! We noticed that some of you running older LXC containers (like Debian 11) experienced the server not starting back up after using the new auto-updater. This happened because the binaries were built on a newer Ubuntu version, requiring a newer glibc. This release fixes that! I've downgraded our GitHub Actions builder to an older, much more compatible Ubuntu version. Also, this release correctly tags the dashboard version so it accurately shows v1.3.7.2 instead of v1.3.6 in the UI! If your server stayed offline, simply re-run your update-amud.sh script to grab this new version and it should bring everything right back online!
