Pin python-version

[dcramer]

Dockerfile is using 3.7, readme says 3.8. Is there a suggested version and should it also be pinned via pyenv (.python-version)?

Good question, that's confusing. All tests are run with 3.7, so I'll update the README to say 3.7.

I'd love to pin the version for the virtual env. Since there doesn't seem to be an equivalent of .python-version for venv, we can prescribe pyenv. Sound good to you?

[dcramer]

Yep - I can propose some other suggestions that we often use @getsentry to make devenvs easier to manage

@dcramer I'd greatly appreciate that! There are still some warts in here from the closed-to-open-source switch, but it's quite stable as the core our customers are using constantly every day.
