I recently spun up a dev environment for contributing a PR to plotly.py and ran into some issues that I think can be addressed fairly readily.

1. pytest is pinned to 3.5.1 in packages/python/plotly/optional-requirements.txt and this version simply didn't run, failing with an internal TypeError. I upgraded it to 7.4.2 and it worked. Is there a reason its pinned to such an old version? can this be unpinned?
2. contributing.md does not currently mention the dependancy on Plotly Orca. I was rather surprised to come back to all my tests failing, and somewhat hilariously the orca Ubuntu screen reader reading a large chunk of Pytest's terminal output to me. Just adding an external dependency in the testing section would do the trick I reckon.
3. There were a number of missing packages required by optional tests that aren't in packages/python/plotly/optional-requirements.txt so those tests failed. The following packages need to be added: polars vaex scikit-image statsmodels pyarrow

btw for 1,the error thrown by pytest 3.5.1 is:

  File "/home/ned/.pyenv/versions/3.11.6/envs/book/lib/python3.11/site-packages/_pytest/assertion/rewrite.py", line 332, in _rewrite_test
