The `component-hook-factories` rule was removed in #35825 as part of a
feature flag cleanup, but was listed in the README as part of the manual
config example. This broke users who used a manual config (copied from
the old README) in eslint-plugin-react-hooks 7.1.0. This adds back a
deprecated no-op rule as a fix.
#35825 removed other rules (`automatic-effect-dependencies` and `fire`),
but these were for experimental features that did not ship. These were
also not referenced in the README.
