This MR provides support "ecdsa-sk" and "ed25519-sk" SSH keys.

In https://gitlab.com/gitlab-org/gitlab/-/merge_requests/77374,
   https://gitlab.com/gitlab-org/gitlab/-/merge_requests/77403,
   https://gitlab.com/gitlab-org/gitlab/-/merge_requests/77996,
   https://gitlab.com/gitlab-org/gitlab/-/merge_requests/77424,
   and https://gitlab.com/gitlab-org/gitlab/-/merge_requests/78532 we have done
   the work that facilitates support "ecdsa-sk" and "ed25519-sk" SSH keys.

By adding support "ecdsa-sk" and "ed25519-sk" SSH keys, we provide a new,
more secure, and easy-to-use way to strongly authenticate with Git
while preventing unintended and potentially malicious access.
For instance, if a user's private key file on their computer is stolen,
it would be useless without the user's security key.
