initial v5 plans

[ljosberinn]

• fix getDependencies called twice #665
• implement FlatConfig
  • can technically be implemented prior, as its already available via configType: 'flat'. but eventually once this is the eslint default (v9?) its going to be a breaking change for this aswell
• fix readme #622
  • which also includes updating the readme to v5
• Consider eslint-plugin-css-modules #573
• evaluate eslint-plugin-etc #593
• Consider to add eslint-plugin-deprecation #551
• [ ] eslint-plugin-regexp #311
• allow standalone generation to have the same customizability as the so-far canonical way
  • make it the default?
