Allow non-superusers to use the script.

[transcental]

On my computer I am not a administrator/super user so can't run gem install bundler
However, I edited the file to have bundle config set --local path 'vendor/bundle' and that worked fine for me.
And this is better as it is only available for the users who actually need it.

Hope this is a good proposal!

I am using MacOS Catalina 10.15.7 so I don't know and can't test if it works on other operating systems. But I think that it should.
