Outline does not show return type for Golang files

[cmprmsd]

Is your feature request related to a problem? Please describe.
Currently the outline shows argument types for functions in the current file. However, the return types are not listed.

E.g. see this outline:

where the function itself has []byte as return type.

Is this something you consider useful?

Describe the solution you'd like
The outline should show return types.

Side note: It'd be also nice if the global variables could be collapsed (maybe even default or globally or for a workspace)
