[PATCH] CI: Update to using grub-2.14 for our tests

[Tom Rini]

When building grub-2.12 with a newer GCC, we run in to warings (treated
as errors). The simple fix here is to move to the latest release tag. In
order to build a newer grub from source we need the autoconf-archive
package to be installed.

There are compiler problems to resolve before CI can move up to
gcc-15.2.0 but this step will be required.
