Allow setup-gpg.sh --import to receive, trust, and add to configure multiple public keys at once

[P-EB]

Hello,

While the whole bastion logic seems to allow for multiple admin keys, the import system doesn't allow for it as it only keeps the latest added key, only trusts this one and then add it to the rsync/backup configurations (and refuses to run more than once as soon as these configurations exist).

While it's not perfect as it doesn't handle the multiple layers considered in the rsync system, this patch should give bastion users plenty more flexibility to handle admin keys addition.

You might want to rebase over current master, which will give you nice tools for a dev environment, including pre-commit hooks to ensure that your code validates perlcritic/perltidy/shellcheck locally :)

Corresponding doc is here https://ovh.github.io/the-bastion/development/setup.html#git-pre-commit-hook

I'm interested in hearing about any feedback you may have on this, it's supposed to be pretty quick to setup!

Thanks!

I've enabled the hook now, I'll see how it behaves in the next commits. :)

FreeBSD workflow is broken due to the GitHub vmactions workflow being stuck in a boot loop as can be seen here vmactions/freebsd-vm#74 .
Will fix this in another PR.
