This isn't great, but I don't know how to get around this - there seems to be a version of dotenv installed already that doesn't play nice with the dependency that's expected.

I think it's probably more important to the basics merged here than deal with the warning, so maybe for now remove -Werror and just keep an eye on the warnings in the pytest summaries, and worry about this later?

Yeah, I'm trying one last thing. If that doesn't work out, I'll drop -Werror.

Ready to be reviewed.

Notes:

• Specifying warning options (e. g. -Werror) in the pytest call seems to overwrite warning options configured somewhere else (e. g. in pyproject.toml).
• The regex to capture only DepreciationWarnings with pgk_resources in it didn't quite work, so for now we're ignoring all DepreciationWarnings (will create an issue to fix this in a later version).

Looks good to me - agreed with prioritizing getting this merged first, and working more on the warning filters later. Would appreciate a final review by Adriane as well 🙏

[update: I'll go ahead and merge this for now so we can continue to build on it]

And thanks again to @adrianeboyd for your help with this!
