Customize flat config

[domoritz]

I am using the new flat config format (https://github.com/prettier/eslint-plugin-prettier?tab=readme-ov-file#configuration-new-eslintconfigjs). However, there seems to be some conflict where trailing command are added by prettier but eslint throws an error. I would like to override some options in the prettier eslint config or have ti use the prettierrc file. It would be great if you could add the missing documentations for how to do that.

This is my project in case something is wrong with my config: https://github.com/vega/ts-json-schema-generator/commit/6e4f40df89afe26b1309b26976888286d2b91f2c
