build: move cleanupNodeModules to its own file

this is necessary, since for Docker and electron-forge, we need to run this as an extra step after copy-dist

for electron-forge: after it is done with its own "pruning", as we otherwise would need to also take care of certain electron related pruning

for Docker: as a last step in the build stage
