Update the `requirements-*` files.

In order to update mypy==1.0.0 we need to also update
responses==0.22.0

Fix one issue found by `mypy`

Leaving updates for `precommit` to be done in a separate commit by
someone.

Authentication issues are currently hard to debug since `--debug` only
has effect after `gl.auth()` has been called.

For example, a 401 error is printed without any details about the actual
HTTP request being sent:

    $ gitlab --debug --server-url https://gitlab.com current-user get
    401: 401 Unauthorized

By moving the call to `gl.enable_debug()` the usual debug logs get
printed before the final error message.

Update code so that the `warn_return_any` check passes.

Add a custom argparse help formatter that overrides the output
format to list items vertically.

The formatter is derived from argparse.HelpFormatter with minimal changes.
