Update eslint to v9 (#35485)

Update eslint and all plugins. Many plugins still do not ship type
definitions so I had to add stubs. Also, I had to put a few typescript
error expectations because if some unknown error in the types.

`eslint-plugin-no-jquery` is disabled because it's not compatible with
eslint 9 flat config
(https://github.com/wikimedia/eslint-plugin-no-jquery/issues/311).
