go: improve outline queries to get rid of whitespace (#7273)

Thorsten Ball created 2 years ago

This changes the Go `outline.scm` queries a bit so that we don't have
these stray whitespaces floating around. I'm sure there's more
improvements possible, but for now I think this makes it look less
wrong.

Release Notes:

- Improved outline and breadcrumbs for Go code.
