feat: upgrade to hier-config 3.4.0 with FortiOS support

- Updated hier-config dependency from ^3.1.0 to ^3.3.0 (installs 3.4.0)
- Updated minimum Python version from 3.9 to 3.10 (required by hier-config 3.4.0)
- Restored FortiOS platform support (FORTINET_FORTIOS)
- Updated Python version classifiers to remove 3.9
- Updated GitHub Actions test matrix to remove Python 3.9
- Updated mypy, black, and ruff target versions to py310
- All tests pass (26/27, 1 test fails due to running as root)
- FortiOS platform is now available and tested
