fix(ci): Correct Forgejo Actions template syntax for git clone auth

Use proper Forgejo variables: gitea.server_url, gitea.repository
Construct CLONE_URL correctly: https://user:token@host/repo.git
Use bash parameter expansion to strip https:// prefix

Removes invalid Forgejo filter syntax (| replace)
