Exclude the docs from the published package, please

[davidrapan]

Ref and request from home-assistant/core#155255 (comment):

I really don't think it's a good idea to add a requirements exception.
This is used to track "existing" violations, not to enable new violations to come in.

You should raise an issue on aiomysql repository to ask them to remove the docs from the published package.

Possibly linked to tool.setuptools.packages.find:

aiomysql/pyproject.toml

Lines 60 to 61 in 72a4df6

	exclude = ["tests", "tests.*"]
