bug(docs): inconsistent docs display in hover

[gnikit]

The lsp/hover signatures for the resulting docs between a() and b() is inconsistent.
One appears to be constructing the full Markdown doc string while the other one just displays the raw doc.

Minimal example:

program main
    ! type a or be here:
    print*, a()
    print*, b()
contains

function a()
    !! this shoes up
    logical a
    a = .true.
end function

logical function b()
    !! this doesn't
    b = .false.
end function

end program main
