Enable enforcing pydocstyle rule D213 in ruff.

[ferruzzi]

Currently we have rules D212 and D213 on the ruff ignore list in pyproject,toml. They are conflicting rules and I want to propose that we work towards enabling one of them. In a nutshell:

class Banana():
"""This is a D212-style docstring.
Note that the summary line of a multi-line docstring is the first physical line, immediately following the opening triple-quote.
"""

class Apple():
"""
This is a D213-style docstring.
Note that the opening triple-quote is followed by a newline in this multi-line docstring, giving the mandatory (per D205, which we already enforce) one-line summary its own line.
"""

Personally, I always use D213 style when I write multiline doc strings and I find it easier on the eyes. When I enabled it and ran static checks, ruff actually auto-fixed all instances so this is an easy one to enable if we want to.

Changes

• pyproject.toml - Manually moved D213 from the exclude list to the run list and added the comments about conflicting rules.
• Ran static checks locally and ruff automatically modified all other files.

I did the same change locally with ruff and compared to this branch - no other changes in here.
