easier Proton logging
I game on Linux and occasionally games don't work for random reasons that are fairly easily solvable but one of the barriers to solving it is getting the Proton logs. It's currently not *that* hard, you have to add the logging environment variable to the run command, but it would be nice if it was easier to access.

Main current pain points:

1. I always have to look up the command and where the logs are stored
2. I need to reproduce the issue again with the logging enabled before I can debug it
3. The workflow to get logs is complicated enough that it's been a pain to help a less technical friend debug issues while in a Discord call

Examples solutions (I haven't thought about UX here much but these are illustrative of the sort of things that would work well for me):

1. The most recent proton log is always available at like /var/log/proton/latest.log
2. If you right click a game in the library and go to Properties -> Compatibility there is a little button that says "View latest Proton log". If we don't want to keep the most recent log always there also could be a little checkbox that says "keep most recent Proton log"
