fix(eslint-config): Clashes with prettier (#26847)

Summary:
Currently, react-native-community config package extends from prettier/recommended which comes with default settings from prettier. However there are still some eslint rules in the config that either clash or duplicate the settings from prettier.

This results in eslint fixing the formatting and then prettier undoing it. This PR removes the style specific rules from eslint and place them in the prettier section.
## Changelog

[General] [Fixed] - Remove style rules from eslint config for prettier options
Pull Request resolved: https://github.com/facebook/react-native/pull/26847

Test Plan:
I created a repo for you to test with https://github.com/iRoachie/eslint-bug-replicate. You can see that running `yarn lint --fix` will never fix the issue. Eslint will complain about double quotes and subsequently after fixing it will complain about single quotes.

Here's a gif of the behaviour (vscode eslint plugin `"eslint.autoFixOnSave": true`):
