fix(plugin-react): remove querystring from sourcemap filename

[frandiox]

Description

The variable used in this sourcemaps fix in plugin-react might contain a querystring, in which case it does not work. This PR removes the querystring passed to Babel.

Additional context

In Hydrogen, some React components end in component.client.jsx?no-proxy and it shows the warning sourcemap for xyz points to missing source files just like in #5438 due to this querystring.
