chore: adopt the NAPALM driver standard

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; .github/ is gone.
- setuptools>=77 with the SPDX license string, no License classifier,
  Python 3.13 classifier, napalm-device-types>=4.21.1, a dev extra with
  floors, Issues and Changelog links; README installs from PyPI and links
  pyVmomi on PyPI.
- mypy strict for the package (the blanket ignore_missing_imports is now
  limited to napalm and yaml); exempt for now (35 errors): _inventory,
  _session, _tasks, base, esxi, parse.environment, parse.snapshots,
  parse.vm_devices, provision.seed, provision.transfer, provisioning.
  Recorded in the quality baseline with the long and complex functions.
- Coverage floor 97 % (measured 97.11 %).
