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), CHANGELOG,
  py.typed, SPDX license string, Issues and Changelog links; a dev extra
  with floors.
- napalm-device-types >=4.21.1 is declared: officeconnect.py imports
  SwitchDriver and FingerprintRule from it, but the package did not list it.
- urllib3 gets a true floor (>=1.23): unbounded, the lowest job installed a
  version that does not import on Python 3.10.
- mypy strict for the package; napalm_hpe_officeconnect.officeconnect is
  exempt for now (4 errors: three ClassVar fingerprint attributes the base
  declares as instance variables, one bare dict), recorded in the quality
  baseline. Coverage floor 91 % (measured 91.83 %).
