Sign Git tags with SSH keys

Release notes

Problem to solve

#343879 (closed) allows Git commits to be signed with SSH keys. Users of this feature would also like to be able to sign Git tags with SSH keys.

Currently, SSH signed tags are not supported by GitLab.

source

Previously, it was an attempt to add SSH tags signature support but it was not completed.

Proposal

Add support for SSH signed tags similarly to existing X509 tags (see X.509 implementation).
