Allow to pass ext to the CLI

[JCMais]

Looks like currently it's impossible to set the --ext argument of the CLI, this is important when using TypeScript.

Sorry if I'm wrong, but I was able to get sourcemaps with TypeScript working without having to manually set the ext argument. Is there another reason for using ext?

This can be an issue when you want to upload .ts files to Sentry; however, I think that is it better to have the source inlined in the .map file, right?

Would be great to upload ts files too.
I used this workaround though in my tsconfig.json:

{
  "compilerOptions": {
    "inlineSourceMap": true
  }
}

The TypeScript SourceMap guide says to inline the source map and this doesn't support the ext ?

Is there any update on this?

this feature is critical to support jvm languages such as Scala.

Can this ticket get some love? Currently it seems to be impossible to use this action for anything but Javascript.
