Linux: Fix AssetBundleManager.GetAssetVersion only working sometimes

[regalialong]

On Linux, the cache version directories are lowercase but versionHex here is completely uppercase. This would be fine on case insensitive systems but ext4 isn't, hence it will fail the existence check later on in CheckVRChatCache.

The annoying part is that if the version hexadecimal does not create letters, the check can work as intended :))))

You don't know how much """"""fun""""""" this was to debug this without a project.

Untested on Windows so please check

Oh yea these sorts of bugs are the worst to hunt down.

Oh no, finding it was fine, I figured it was something along the lines.
The actual issue is that the only valid project that Rider takes it the CEF project, the Electron project refuses to load

so I can't do breakpoints in the actual files, I need to attach, halt, and then ask it to disassemble the app dll, then make breakpoints there
