generate gitea token

[nabuskey]

This PR makes idpbuilder generate a Gitea admin token. This is useful for use cases such as:

• Cloning Gitea repositories.
• Performing some sort of Gitea related operations. e.g. configure webhook for a repository.

Partially fixes: https://github.com/cnoe-io/idpbuilder/issues/378

Example output:

./idpbuilder get secrets -o json -p gitea
[
  {
    "name": "gitea-credential",
    "namespace": "gitea",
    "data": {
      "password": "E_aaaaa'",
      "token": "aaaaaa",
      "username": "giteaAdmin"
    }
  }
]

What is the duration of the Token ? Can a user renew it ? @nabuskey

No expiration. I don't think Gitea supports it until they move to JWT: https://github.com/go-gitea/gitea/issues/4793
