Support for GitLab

[lukeburciu]

Proposing adding support for GitLab, this flows like:

$ keycutter create gitlab.com_lukeb@lukeb --type ed25519-sk                                                                                                                                            
❓ Append the current device to the SSH Keytag? (gitlab.com_lukeb@lukeb). (Y/n) n
Proceeding with original ssh_keytag: gitlab.com_lukeb@lukeb
➕ Generating FIDO SSH key: /Users/lukeb/.ssh/keycutter/keys/gitlab.com_lukeb@lukeb
Generating public/private ed25519-sk key pair.
You may need to touch your authenticator to authorize key generation.
Enter PIN for authenticator:
You may need to touch your authenticator again to authorize key generation.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/lukeb/.ssh/keycutter/keys/gitlab.com_lukeb@lukeb
Your public key has been saved in /Users/lukeb/.ssh/keycutter/keys/[email protected]
The key fingerprint is:
SHA256:... gitlab.com_lukeb@lukeb
The key's randomart image is:
+[ED25519-SK 256]-+
...
+----[SHA256]-----+
❓ Upload public key to GitLab for auth using GitLab CLI? (Y/n)  Y
Logged in as lukeburciu.
❓ Do you want to switch to another GitLab account? (y/N): N

➕ Add SSH authentication & signing key (/Users/lukeb/.ssh/keycutter/keys/[email protected]) to GitLab
✓ New SSH public key added to your account.

⚠️ Note: Enforce SSO-only authentication for Git and Dependency Proxy will require additional setup.
❓ Symlink key to enable ssh.gitlab.com:443? [Y/n] Y

➕ Creating symlink: ln -sf /Users/lukeb/.ssh/keycutter/keys/gitlab.com_lukeb@lukeb /Users/lukeb/.ssh/keycutter/keys/ssh.gitlab.com_lukeb@lukeb
✅ Success! Setup complete for key: gitlab.com_lukeb@lukeb

It proposes a change in how:

check-service in bin/keycutter works.
