  Setup Forgejo and a runner.

  If `binary` is specified, Forgejo downloads the binary from the URL and uses
  it to start an instance.

  Otherwise, `image` and `image-version` must be specified and Forgejo
  runs from the corresponding container image using docker.

  The forgejo-test-helper.sh script is available to help test and debug actions.

  `forgejo=http://root:admin1234@${{ steps.forgejo.outputs.host-port }}`

  * `forgejo-test-helper.sh push_self_action $forgejo root myaction vTest`
    Creates the repository `$forgejo/root/myaction` and populates it with the
    content of the repository under test, except for the `.forgejo` directory
    (it would otherwise create an infinite loop). The tag `vTest` is
    set to the SHA under test.
  * `forgejo-test-helper.sh run_workflow testrepo $forgejo root testrepo myaction`
    Creates the repository `$forgejo/root/testrepo` and populates it with the
    content of the `testrepo` directory. All occurrences of `SELF` in
    `testrepo/.forgejo/workflows/*.yml` are replaced with `$forgejo/root/myaction`.
  * `forgejo-test-helper.sh push testrepo $forgejo root testrepo`
    Creates the repository `$forgejo/root/testrepo` and populates it with the
    content of the `testrepo` directory.

  The combination of `push_self_action` and `run_workflow` allows to
  run Forgejo Actions workflows from `testrepo` that use the action
  under test (`myaction`) to verify it works as intended.

  The [forgejo-curl.sh](https://code.forgejo.org/forgejo/forgejo-curl#forgejo-curlsh)
  script is logged in the instance and ready to be used with web or api endpoints.
