GitHub action for zip+MLTBX: Move files to managementtools subfolder.

Move M-file and project file to managementtools subfolder, to
declutter the root folder.

Some white-space and indentation cleanup and comment improvements
in the .github/workflows/buildZipMLTBX.yml file.

-> No real functional change intended, just cosmetics.
