Remove scripting that attempts to find and install node

[emlowe]

Similar to what was done with python some time ago - eliminate the code in the install-gui script that tries to find and install node. This simplifies the script considerably, and it places the burden on the user to make sure they have the proper version for their OS

Since our CI always make sure the runners have the proper version of node installed this change has no affect on CI. Very few users try to install the run the GUI from source so this has limited impact to actual users - and those users can easily get NodeJS from official channels

The trigger for this change was problems the script was having using brew to install node on macOS 13. Rather than change it to use alternative means, this change is simpler and removes a bunch of scripting and follows along with the precedent we made earlier for python

💛 - Coveralls

The new install script works when node and npm are installed.
However, it doesn't work as expected on the environment where neither node nor npm cannot be found.

Thanks for testing that @ChiaMineJP - I missed that case

[emlowe]

@ChiaMineJP I believe I have fixed up the script to handle this case now

[ChiaMineJP]

Now it looks good to me 👍
