Subject: [PATCH] feat(build): convenience for packaging build for beta,
 details follow (#5154)

Use `yarn package:beta` to package an app build pointing to beta.

* Does not require modifying code anymore.
* Does not require user intervention (i.e. setting env vars before
  running the app).
* Executable name is renamed to "Streamlabs OBS for Beta".
* Forces local bundles, without it your development branch would likely
  be overwritten by the updater using remote bundles.
* Compiles in development mode so that compilation is faster and we can
  troubleshoot non-minified logs.
* Tested on Windows, Mac PR welcome :)
