Use Case

As an eslint user,
I want to adopt eslint v9's flat config file format for my eslint configuration,
So that we can continue to update eslint once the legacy config format is removed in v10.

Eslint v9 substantially changed the configuration file format. Adopting eslint v9 without migrating our config files is possible using the new ESLINT_USE_FLAT_CONFIG environment variable, but support for this compatabilty layer will be removed in eslint v10.
