Documentation - Add description how to use it with Steam on Linux/Proton

Description

As a user I would like to know how to use AML on Linux with Proton.

For context: I've recently installed XCOM2 and saw, that the Workshop-Mods are not working. The "old mod manager" lists no mods. The "new mod manager" doesn't even open. That's where I came across this project.
You're doing a great job and it works fine!

Suggest a solution

I would like to have some information in the Readme or the Wiki how to use this project on Linux with Proton, which is provided by Steam. In my case I did the following steps:

• Open XCOM2 folder via Steam (find local files). It should be located in ../steamapps/common/XCOM 2/.
• Create a folder Launcher_Alternative (in my case: ../steamapps/common/XCOM 2/Launcher_Alternative).
• Download and extract the zip-file (Releases) into Launcher_Alternative.
• Open Steam.
• Choose Menu > Games > Add Non-Steam Games to a Library.
• Pick ALM (e.g. ../steamapps/common/XCOM 2/Launcher_ALM/launcher.exe).

Now it's listed in your library as launcher.exe.
Right click on it Settings > Compatibility and choose a specific version of Proton. I've tried 9 (steam default and GE-9-27) and 10 (steam default and GE-10-8). Use play and the launcher opens.

It lists all my mods and with the checkboxes I can turn them on and off. By pressing "Run WOTC" the game starts. Maybe this helps some people who have issues to get started with ALM on Linux.

Additional notes:

My system is Kubuntu 24. And a screenshot as proof :) All I did was launching ALM, activate the checkboxes and press play. No console-hacking was required so any user should be able to do this.

May refer to: #171

Thank you for your input. You should be able to edit the Wiki, access is not restricted. So maybe create an entry in the "advanced" or "unofficial guides" section.
There have been several discussions regarding AML and Linux in our Discord and I think there is some guide on Reddit. It would be nice to consolidate all the information and provide a comprehensive guide at some point.

PS: I will move this issue to discussions,
