Docs: eslint instructions are still for v8

[MonstraG]

What is the documentation issue?

Documentation page for eslint config - https://nextjs.org/docs/app/building-your-application/configuring/eslint - still describes how to set everything up with Eslint 8.

So far I tried to follow #71763 (comment) instead (I don't wanna use the compat mode), but

TS7016: Could not find a declaration file for module @next/eslint-plugin-next.

Is there any context that might help us understand?

This is sort of duplicates #71763, but technically not, as that one is about what you get installed, and this one is about docs, and for me the docs matter more.

Does the docs page already exist? Please link to it.

Maybe adding this npm command to the doc would also help. it saved my day 👍

@MonstraG you can use // @ts-expect-error There are no types to mitigate that error. Most of my eslint plugins don't have types
