ci : use github ubuntu-22.04-arm runner instead of qemu (#3815)

* ci : use github ubuntu-22.04-arm runner instead of qemu

This commit updates the ubuntu-22-gcc-arm64 job to use a arm github
runner instead of QEMU.

The motivation for this is that we get intermittent failure specifically
related to QEMU. For example:
```console
Segmentation fault (core dumped)
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
dpkg: error processing package libc-bin (--configure):
installed libc-bin package post-installation script subprocess returned error exit status 139
Processing triggers for ca-certificates (20240203~22.04.1) ...
Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.
Errors were encountered while processing:
libc-bin
E: Sub-process /usr/bin/dpkg returned an error code (1)
```
This is an attempt to try to avoid QEMU and hence avoid this issue.

* ci : remove QEMU where possible
