Revert #34719

Adds back HermesParser to eslint-plugin-react-hooks. There are still [external users of Flow](https://github.com/facebook/react/pull/34719#issuecomment-3368137743) using the plugin, so we shouldn't break the plugin for them. However, we still have the problem of double parsing: once from eslint (which we discard) and then another via babel/hermes parser.

In the long run we should investigate a translation layer from estree to babel (or alternatively, update the compiler to take estree as input). For now I am reverting that PR.  This does mean that [Sandpack in react.dev](https://github.com/reactjs/react.dev/blob/11cb6b591571caf5fa2a192117b6a6445c3f2027/src/components/MDX/Sandpack/runESLint.tsx#L31) cannot update to the latest eprh as HermesParser does not appear to be able to be run in a browser. I discovered this while trying to update eprh on react.dev last week, but didn't investigate deeply. I'll need to double check that again to find out more.
