[mcous]

Overview

Closes #9931. See ticket for more details. Decided to tackle this now to ease onboarding of new Python contributors by removing useless busywork.

Changelog

• style(python): remove line length limit from flake8 config

Review requests

• Your local editor handles these config changes
  • Note: if your editor does not hook into flake8, you may need to change some settings manually to ignore E501
• Your local make lint handles these config changes
• CI handles these config changes

Risk assessment

Low due to the nature of the change (lint config + comment removal). When you're skimming the diff, make sure you only see removals of noqa: E501 in the diff.
