In attempting to add our reusable mypy action to this repo, I'm running into the following issue when mypy attempts to install type stubs (via the --install-types option):

Installing collected packages: urllib3, types-requests
  Attempting uninstall: urllib3
    Found existing installation: urllib3 1.26.19
    Uninstalling urllib3-1.26.19:
      Successfully uninstalled urllib3-1.26.19
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
botocore 1.35.94 requires urllib3<1.27,>=1.25.4; python_version < "3.10", but you have urllib3 2.3.0 which is incompatible.

When I ran into this error for https://github.com/ASFHyP3/hyp3, the easiest resolution was to upgrade beyond Python 3.9. I haven't investigated other ways to resolve it, so I'm not sure how difficult it would be to address this issue without first addressing #300

Nevermind, it was easy; just add types-requests to environment.yml so it gets installed with the other dependencies.
