fix: bot and web_api build

[chdsbd]

The Poetry install for purest was failing because it's dependency, pluggy was failing to install because it's dependency, zipp was failing to install.

Bumping the pytest version fixes the install, but I also needed to upgrade pytest-asyncio to fix a deprecation error.

Looks like we might need to upgrade our poetry version to avoid that runtime bug: https://github.com/python-poetry/poetry/issues/4409#issuecomment-903173358
