text: fix pytest config

pytest was using config from `tox.ini` preferentially and ignoring config
from `setup.cfg`, as a side-effect doctests were not running on
code/docstrings in `rdflib/`.

The reason why some pytest config was in `tox.ini` instead of `setup.cfg`
was because of these issues:
- pypa/pip#5182
- pytest-dev/pytest#3062

As a compromise to fix this I have opted for moving all pytest config to
`pyproject.toml`:
- https://docs.pytest.org/en/stable/reference/customize.html#pyproject-toml

This seems sensible as `pyproject.toml` is standarized by PEPs and
eventually most things from `setup.cfg` will end up in there anyway.

Also:
- remove the pytest ignore on `test/translate_algebra` as tests in there
  have been running and passing for some time.
- fixed path to test data in `rdflib/plugins/parsers/nquads.py`.
