Support ESLint "flat" configs

[G-Rath]

Yeah we've had #1245 open implementing support, but everytime I sit down to try to make sense of the new flat config the docs always seem to be missing parts (and it is still actively being worked on) - as you've said it's pretty easy to work around for now.

Having said that it's been a while since I last looked at it, so I'll bump it up my todo list to try have another go next month.

The new flat config docs are definitely missing parts, which is not helping the transition to the new flat config approach. The docs should be in line with the running code.

Alpha for v9 is out, it's probably time to implement support: https://github.com/eslint/eslint/releases/tag/v9.0.0-alpha.0

Appreciate it! If there's anything I can do to help with testing / validation / etc, let me know.

I've found this doc to be pretty solid for end-user usage. But to your point, for plugin authors it could use some work.

@G-Rath This would be amazing to have, also would necesitate generating d.ts files upon build.
