Markdown linter

[jprochazk]

What

• Closes Check our markdown files for syntax errors #4007

Adding a very basic markdown linter. Currently covers only a few issues.

Running pixi run mdlint will check all markdown files in the current directory.

Every error has an error code, which can be used to explain the error via pixi run mdlint --explain {code}.
