ci: replace buildjet arm64 runners with actuated ones

The CNCF signed a contract with Actuated to provide free arm64 runners
to CNCF project: see https://actuated.dev/blog/arm-ci-cncf-ampere.

After some trial and error we managed to compile a kernel for the
runners using Firecracker that works with BPF and especially Tetragon.
Only limitation is that they are running 5.10 for now and there is no
nested virtualization. But good news is that we can get more CPU and
more RAM for free!
