chore(hardware): Remove docstring content checks (#12128)

These were mostly annoying and entirely surface level and trip up so
many PRs and who cares.

The removed ones are

D400 | First line should end with a period
D401 | First line should be in imperative mood
D401 | First line should be in imperative mood; try rephrasing
D403 | First word of the first line should be properly capitalized
D404 | First word of the docstring should not be This
D415 | First line should end with a period, question mark, or exclamation point
D105 | Missing docstring in magic method
