fix(pytest): asyncio property errors (SchemaStore#4570)

Fix errors flagged due to properties in pytest section of pyproject.toml
when asyncio options are configured.

The additional properties were defined based off the pytest-asyncio
configuration specification here:
https://pytest-asyncio.readthedocs.io/en/latest/reference/configuration.html
