docs(eslint-plugin-react-hooks): clarify config details for prior versions (#32498)

This change adds more details about prior versions of the plugin's
config, to help people as they migrate from legacy to flat configs
across multiple versions of this plugin. At some point in the 6.0 or 7.0
cycle, it would probably make sense to re-consolidate this into a single
version.

Closes #32494
