Pin runtime and test dependencies (#316)

* build: Extracted runtime dependencies finto requirements.txt.

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

* build: Removed upper version bound on pytest dependency.

Constrained pytest to v7.1.1.

* build: Added version constraints for transitive dependencies of the "testing" extra.

* build: Added version constraints for dependencies to the "pytest-min" tox environment.

* build: Extracted runtime dependencies from pytest-min tox environment into the file pytest-min-requirements.txt.

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

* build: Added missing explicit dependency on typing-extensions to pytest-min-requirements.

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

* ci: Move different sets of constraint and requirement files to different directories.

This allows Dependabot to update both dependency sets independently.

* build: Removed upper bound on the mypy version installed by the "testing" extra.

Adjusted constraints accordingly.
