[CI/CD] macOS Universal2 builds via GitHub Actions

[taysta]

Changes:

• Adds macOS universal2 builds to the GitHub actions workflow, providing a build that will run on both x86_64 and arm64 macOS systems
• Updated Info.plist files

Other considerations I noticed while doing this, which are relevant but I have decided are out of the scope of this PR for now:

• The module and renderer dylibs have the architecture extension hardcoded, so we can't lipo the modules and renderers together into a single ub2 version as the engine will try to find files with extensions matching the architecture of the current user, currently I am just bundling both the x86_64 and arm64 module and renderer dylibs into the universal2 bundle, but we could save on filesize by either removing the architecture extension requirement when loading, or by allowing a ub2 extension to work on both x86_64 and arm64 macs
• Currently, there are 3 copies of the info.plist file, could this be one file

Notes:

• I have tested and confirmed that openjk mp, openjk sp and openjo sp are all working on arm64, but I do not have access to an x86_64 system to verify them there.
• A consideration to make while reviewing is that create-latest and create-release cannot be tested without the merge triggering the release, and this PR does introduce changes which could potentially cause them to break upon merge, I am pretty sure the zip filenames are correct, and the needs: steps have the added macos-ub2 dependency, so I believe they will run successfully, but worth double checking.
