remove space from line label so they are clickable

[AlexanderHott]

The current formatting for file + lines isn't picked up by the vscode file regex, meaning you can't click it to navigate directly to the location.

This PR changes the formatting from

path/to/file: 42, 44, 46

to

path/to/file:42
path/to/file:44
path/to/file:46
