chore: adopt the NAPALM driver standard

- The distribution is renamed to napalm-netgear-switches: napalm-netgear
  on PyPI belongs to another project. The import package napalm_netgear
  and the napalm.drivers entry points netgear_smart and netgear_plus stay;
  [tool.napalm-standard] package names the import package for the check.
  README install line and CHANGELOG say the new name.
- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; .github/ is gone.
- requires-python >=3.10 (napalm-device-types needs it), floor
  napalm-device-types>=4.21.1, LICENSE file, py.typed, SPDX license string,
  links to git.netork.io, a dev extra with floors, CHANGELOG.md.
- mypy strict for the package; napalm_netgear.netgear_plus and
  napalm_netgear.netgear_smart are exempt for now (139 errors), recorded
  in the quality baseline with their long and complex functions and the
  2070-line netgear_smart module. Coverage floor 48 % (measured 48.23 %).

Closes #14
