chore: switch to isort from reorder python imports

[jmeridth]

So many files changes. "Gotta rip the bandaid off" 😄

• [x] keep it simple with just --profile black argument
• [x] update pull_request_template when asking for python-dateutil version
  • some engineers don't know to prefix dateutil with python-

This is a premptive strike on #1172 fix

Doesn't isort have a config for an import per line like reorder python imports?

[jmeridth]

That was not an issue locally:

✗ black src/github3/repos/branch.py
All done! ✨ 🍰 ✨
1 file left unchanged.

But I'll take it fixing it and now this is passing.

@sigmavirus24 nice change with force_single_line = true. Definitely less churn.
