install_dependencies.py appears to be broken

[WickedShell]

I know I've used this script in the path with some slight issues and success, but it's no longer working.

I'm not sure what's supposed to be in rts-sources.json here at this point. I'm also unsure if this is more a problem with the bb-runtimes repo, or not having prepped all the files before trying to install the bb-runtimes.

This looks similar to: AdaCore/bb-runtimes#42

See my answers there and make sure you have the compilers in your PATH.

If you have multiple Ada installations if your PATH, they need to be in the correct order. It appears that gprls only looks in the first Ada installation it finds. This is on both MacOS and Windows 10.
