Flush and rebuild vcr, replace pytest vcr with pytest recording

[dannypeterson]

Flushed and rebuilt VCR. pytest-vcr package is no longer supported, so replaced with pytest-recording. Removed urllib3 because it is a dependency of the requests package. A list of changes:

• Updated requirements/dev.txt
• Updated pyproject.toml
• Updated github actions workflow
• Deleted old cassettes and rebuilt with pytest recording, checked with wifi disabled

---

NOTE: this branch requires a few updates to the current dev environment:

python -m pip uninstall pytest-vcr
python -m pip install -U urllib3
python -m pip install -r requirements/dev.txt
