feat: re-export flat configs "flat/*"

[aladdin-add]

long-time plan:

v6: no action
v7: rename flat/* => *; eslintrc config * => legacy/*?
v8~: remove eslintrc supports

I think the plan you've described makes sense and aligns with the recommendation I wrote in eslint/eslint#18095 (comment).

We could also get rid of the direct string imports like require('eslint-plugin-eslint-plugin/configs/recommended') in the next major version.

I think it's fine to keep it, as long as it doesn't come with large maintenance costs. :)

It doesn't have much maintenance cost, but long-term, I still think it's preferable to standardize on a single means of using flat config with the standard configs object.

yes, we can remove them all when dropping the eslintrc supports. :)
