Update CI (#69)

* Add fail-fast to run all scenarios

Without it, first fail cancel all other strategies of the same
job (e.g. fail 3.5, all other versions will not run).

* Use Python 3.10 instead of 3.10-dev

* Update GitHub actions versions

* Add six to test environment

Required by tests/path.py:15 but satisfied by no other package,
causing tox envivonment to fail.
