Automatically wrap admonition code-blocks in linting

Problem

Prettier skips wrapping code blocks. This becomes a problem for Sphinx admonition directives. See this commit as an example:

Description

Write a plugin for prettier, as described by #2348. We need to find some other approach for this (see comment below)

[sarayourfriend]

It's not possible to use a prettier plugin without publishing it or without switching to a local hook for prettier like we use for eslint. That's not really an option, it seems, otherwise we'll be adding pnpm as a dev dependency for the entire monorepo, rather than just the frontend (which is currently the case).
