fix(remix-react): undeprecate `LiveReload`'s `nonce` prop

[kentcdodds]

It was necessary for CSPs before, then it was no longer necessary thanks to https://github.com/remix-run/remix/pull/2783, but then it became necessary again when this PR was merged: https://github.com/remix-run/remix/pull/2874 but the deprecation warning was never removed.

Until this is released, people will get this in their editors:
