Hover tooltip module name is monospace once again

The line separator is moved below the function signature to split
regions between the docs. This is very similar to how IntelliJ
displays tooltips. Adding an additional separator between the module
name and function signature currently has rendering issues.

Fixes #4594
Alternative to #4615
