What are you seeing?

When using the Cake.Git addin on macOS (arm64), the required native binary libgit2-a2bde63.dylib fails to load. The addin attempts to load a binary from the default location (tools/Addins/Cake.Git.4.0.0/lib/net8.0/) that is built for the x64 architecture, which is incompatible with macOS arm64.

However, a compatible binary is included in the package at tools/Addins/Cake.Git.4.0.0/runtimes/osx-arm64/native/libgit2-a2bde63.dylib. Manually replacing the default binary with the binary provided in the "runtimes" directory resolves the issue.

What is expected?

The Cake should automatically detect and load the appropriate native binary for the target runtime and architecture at least for Cake.Git. On macOS arm64, it should load the binary from runtimes/osx-arm64/native/libgit2-a2bde63.dylib instead of using the incompatible x64 binary from lib/net8.0/.

Steps to Reproduce

1. Use a Mac device with an M-series chip (arm64 architecture).
2. Create a Cake script that uses the Cake.Git addin.
3. Execute the script with the any supported .NET runtime.
4. Observe the error when the addin attempts to load git2-a2bde63.dylib or libgit2-a2bde63.dylib.

Optional:

• Manually replace the binary in lib/net8.0/ with the one in runtimes/osx-arm64/native/ to confirm that it resolves the issue.
