Revert [eprh] Remove hermes-parser (#34747)

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).
But for now, I am reverting the 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.
