gha: static-checks: Move to the Azure instances

The GHA runners are not exactly powerful, which makes the static-checks
take way too long (almost an hour).

Let's give a try and move those to the same size of Azure instances used
as part of our CI, and probably have this time reduced.

Fixes: #7446
