[BUG] Scripts do not run from directory with spaces in path

[chrismclarke]

Describe the bug
If a user has checked out the repo to a directory that includes spaces, e.g. /my user name/open-app-builder then scripts will fail with non-obvious message No such file or directory: '/user/my' (having split the directory path on a space)

Guidance has been added to the docs to make clear the requirement to use paths without spaces, however it would be good to fix properly

See notes from #2407

To Reproduce
Clone a clean copy of the repo to a pathname including spaces and attempt to sync content from any repo
