[Feature]: Support different extensions for JS files

[Esemesek]

What problem does this feature solve?

Currently, RSDoctor doesn't work correctly out of the box whenever used in Re.Pack projects. It detects no Javascript files, doesn't display Bundle Analyzer Graph at all and probably few other things that I haven't managed to spot. This is most likely caused by React Native using .bundle extensions instead of .js.
I was able to make things somewhat work:

• Bundle Analyzer Graph by patching the webpack-bundle-analyzer

• Javascript files are displayed correctly by hacking JSExtension variable from @rsdoctor/types and changing it from .js to .bundle

What does the proposed API look like?

I just want the plugin to work with RePack projects.

Understood, we will support this later.
