[Feature Request] Investigate/document how to use PyCharm debugger with workflows

[cretz]

Describe the solution you'd like

May be similar to #238 but maybe not (that's more about the sandbox).

It seems when trying to debug via replayer in PyCharm, some things break that work just fine when not using PyCharm's debugger. Investigate what breaks and why. This may be due to some patching/expectations PyCharm has around asyncio that don't hold true for custom asyncio implementations. There's another issue at https://youtrack.jetbrains.com/issue/PY-64542/Asyncio-support-for-the-debugger-doesnt-work-with-pytest-asyncio.

We need to document how exactly to use breakpoints in workflows from this IDE.
