hemtt launch provides incorrect path for workshop mods on native steam on Linux

[LinkIsGrim]

Tools (complete and add to the following information):

• HEMTT: 1.13.2 stable, from install script
• Operating System: Linux

Description: Mods in workshop field from launch.toml aren't loaded using native steam. Using hemtt launch -- -mod=\"Z:/path/to/workshop/450814997\" to load CBA for example bypasses the issue

Steps to reproduce:

1. With native steam, run hemtt launch on https://github.com/acemod/ACE3
2. Get ace_main requires cba_main error when loading. Observe CBA isn't actually loaded in main menu.

Expected behavior: Mods from workshop field to load properly.
