Ability to set line length for markdown cells

[TPreece101]

Description

Hey team, I've been using marimo in a codebase that has some pretty strict pre-commit hooks for linting (ruff). One of those is for line length.

It's great being able to set the line length for code cells but since the markdown cells are also part of the Python script the linter always flags these.

Suggested solution

It would be great if you could set the line length for Markdown and SQL cells so that it doesn't break linting.

Are you looking for an auto-fix on the line-length in markdown cells? Such that we change your markdown code to fix the length?

Not a solution, just an opinion:
Are you referring to the error code E501? My suggestion (which we adopt in the marimo repo) is to still have a line-length so the ruff formatter and trim to that size best it can, but just turn off E501. We have found enforcing E501 will create more unreadable docs or markdown

Yeah it is the E501, and I agree that we should avoid modifying code as much as possible, in thinking of solutions I've realised that I can just add an annotation to the top of my file like this:

# ruff: noqa: E501, E101, F841
