Drop pytest 6.1 compatibility (#482)

* [build] Drop compatibility with pytest 6.1.

Pytest 7 was released on 2022-02-03, roughly one year ago. It is time to bump the minimum version requirement on pytest.

Signed-off-by: Michael Seifert <m.seifert@digitalernachschub.de>

* [refactor] Replace custom type aliases for with pytest types.

The types Config, PytestPluginManager, and Parser are available as part of the public pytest API starting from pytest 7.

Signed-off-by: Michael Seifert <m.seifert@digitalernachschub.de>

* [refactor] Remove deprecation warning when using a pytest version lower than 7.

The minimum pytest version was bumped to v7, so this deprecation warning should never be triggered.

Signed-off-by: Michael Seifert <m.seifert@digitalernachschub.de>

* [refactor] Replace forward reference in event_loop fixture with actual type.

Signed-off-by: Michael Seifert <m.seifert@digitalernachschub.de>

* [refactor] Link to Pull Request for exposing FixtureDef and SubRequest in pytest.
