New contributor to brew - Running into issue on formatting

I am trying to contribute to homebrew formula. I am running into formatting issues because of which my PR is blocked. I am not a ruby dev and haven’t done any ruby. I managed to fix most of the issues.

But there is still one issue which I am not aware of what to do.

Align the keys and values of a hash literal if they span more than one line.

I would appreciate if someone can help me resolve this issue.
