Compatdata Redirect: Add option to only redirect on major Proton versions

[sonic2kk]

Implements #866.

Adds a checkbox on the Game Menu that will only create a new compatdata redirect folder on major Proton version bumps.

The default behaviour right now is to make a new compatdata redirect on each new Proton version, including minor fix versions. So a user could end up with compatdata-proton-8.0-2d, compatdata-proton-8.0-3c, compatdata-GE-Proton8-6 and so on. This new option will only create new compatdata directories for major version bumps, such as compatdata-proton-8.0 or compatdata-GE-Proton8.

SteamTinkerLaunch should be able to automatically pick up and switch to using compatdata-proton-XX over the folder with the minor fix version. In testing going between both of these options worked without issue, the logs also indicated that the compatdata for the game I was testing with was being selected correctly.

TODO:

• Testing from OP who reported the issue
• Update langfiles

Initial testing from OP is looking good, this is probably ready to merge once langfiles are updated, unless anything last-minute comes up.

Updated the description string slightly. ShellCheck is good for this and the version is bumped, so this is good to merge.
