chore: adopt the NAPALM driver standard

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; .github/ goes.
- requires-python >=3.10 (napalm-device-types needs it), LICENSE file,
  CHANGELOG, py.typed, SPDX license string, links to git.netork.io;
  napalm-device-types >=4.21.1, a dev extra with floors.
- [tool.napalm-standard] names the import package napalm_procurve, which is
  not the distribution name.
- True floors for netaddr (>=0.7.10) and urllib3 (>=1.23): unbounded, the
  lowest job installed versions that do not import on Python 3.10.
- mypy strict for the package; napalm_procurve.api_client, .parsers and
  .procurve are exempt for now (136 errors), recorded in the quality
  baseline with their long functions and the 1400-line procurve.py.
  Coverage floor 54 % (measured 54.28 %).
