Git HTTP Auth breaks w/1.14

Upgrading to 1.14.0, and cloning via HTTP auth (username + password) gives this stack trace:

  File "/opt/conda/lib/python3.10/site-packages/pygit2/remotes.py", line 171, in ls_remotes
    self.connect(callbacks=callbacks, proxy=proxy)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/remotes.py", line 120, in connect
    payload.check_error(err)

    raise self._stored_exception

    return f(*args)

    ccred = get_credentials(credentials, url, username, allowed)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/callbacks.py", line 569, in get_credentials
    creds = fn(url_str, username_str, allowed)
  File "/opt/conda/lib/python3.10/site-packages/scmrepo/git/backend/pygit2/callbacks.py", line 51, in credentials
    from pygit2.credentials import GIT_CREDENTIAL_USERPASS_PLAINTEXT, UserPass
ImportError: cannot import name 'GIT_CREDENTIAL_USERPASS_PLAINTEXT' from 'pygit2.credentials' (/opt/conda/lib/python3.10/site-packages/pygit2/credentials.py)

Version 1.13.3 works fine though :).

Thanks.

Comienza comparando las APIs de credenciales de pygit2 1.13.3 y 1.14.0, centrándote en el import en scmrepo/git/backend/pygit2/callbacks.py. Reproduce un clon HTTP con nombre de usuario y contraseña, y verifica después que la autenticación funciona con pygit2 1.14.0 sin el ImportError indicado.
