fix(output): modify --hyperlink output to work properly in WSL

If the environment variable "$WSL_DISTRO_NAME" is set, the hyperlink is
modified so that the file/folder can be opened directly via Windows Explorer.

To open a file in a WSL environmen the link must be as follows:
file://wsl$/${WSL_DISTRO_NAME}/{abs_path}
