Bump Dependencies on Steam Deck

[sonic2kk]

Fixes #719

Initial logic for bumping dependencies to the version SteamTinkerLaunch expects (e.g. bumping from 1.9-5 to 1.9-7). Entirely untested for now.

There is currently no logic for "bumping down", which a user may find useful if they switch between SteamOS versions.

I have been busy and in my free time I have been using my Steam Deck to play some games, so I haven't had time to test this on my Steam Deck yet. I'll try to find some time this weekend to test it out :-)

Finally have some time (woo January over! 😅), taking a look at this again.

The version check was changed to a != check which should accommodate "bumping down" versions. It may not really be used very much but if a user rolls back to an older commit of STL specifically to downgrade a dependency (or a stable, once this change is in a stable release) then it should not require manual intervention to downgrade a dependency.

I want to release a new minor version of STL soon (maybe v12.12? 😉) with a handful of minor fixes and tweaks, and this is one change I would like it to have. Having this in a stable would be nice and allow a good "rollback" point in the event of dependency versions needing bumped for one version of SteamOS but not another.
