[!CAUTION]
Snipe-IT now requires PHP 8.1 or greater

There's always one, isn't there :)

This fixes a framework compatibility issue we missed that no longer uses the static Request::has() facade, and adds some tests to make sure we don't miss that in the future.

If you happen to be running Snipe-IT over a reverse-proxy and when you upgrade, your CSS does not load, try setting APP_FORCE_TLS=true in your .env.
