Windows gradle commands support, VSCode launch.json for placing debug points, and minor doc update

[ambaumann]

This is a mix of small changes for me to get to a build and debug workflow on windows.

• Im newer to gradle, electron, and rollup so any direction on adjusting this PR is welcome.
• Building the source maps through rollup might need to be made contextual but were needed to place VSCode debug points.
• For the VSCode debug profiles, I used: Online Example
• I tested that debug points can be set for the echo app both in the main and the tsx files.
• It is a bit annoying that Windows cant use npm without the "CMD" extension by default.
• The existing package locks were giving me grief specifically with "Error: Cannot find module '@rollup/rollup-win32-x64-msvc'". Maybe it had to do with 4.1.4 vs 4.1.5 on windows. I just regenerated new package lock files. For some reason the license info in the lock files was dropped. Let me know if I need to regenerate them or if there is more detail on how existing lock files are generated.

This difference might be the most impacting one for me to get a working build.

This looks good overall, glad to see you were able to get a windows build working. I'll test it later today and get it merged. The lock files are probably not a big deal but I can test it on a few more systems to make sure.
