Adding newline after all arguments, not after evry single argument in macros

[DipsyTipsy]

Details

Noticed that if you added more arguments to a macro, splunk would complain about the arguments being spread over several lines. Suggesting fix by having the arguments on the same line, with a newline after all the arguments.

Neat PR, thanks for fixing this. We have moved our tooling that generates such file to this new repository. This new tooling is more robust and has more features to control how your yamls behave. Can you perhaps create a PR in this repository, i believe this is the file where you'd want to : https://github.com/splunk/contentctl/blob/main/contentctl/output/templates/macros.j2

Thanks again!
