ESLint v8.53.0 deprecated stylistic rules

[ElSaico]

Too much added complexity and maintenance work in core - for something that's better handled by dedicated formatters - was the stated reason (see: eslint/eslint#17522), with the TypeScript and React plugins following suit.

There are two alternatives for the future, then:

1. @stylistic/eslint-plugin as a 1:1 replacement - an immediate solution
2. Create a new plugin for a tool like Prettier - which has the advantage of handling Svelte as well

Always good to note. Let me know if you see any actual deprecation warnings. I don't use ESLint for code formatting per se, but there may be some long standing rules that I need to redefine / change plugins if necessary.

The TyphonJS ESLint config setup is what I use for development and do have setup in the Foundry TRL demo repos, but it's not a requirement. You are free to modify things as you like for the rules / setup you prefer.

Once the Svelte 5 transition occurs I'll also be evaluating adding Svelte support and more, but waiting on all of that, so quite likely unless there are deprecation warnings the TJS config files will be updated later this year.
