Subject: [PATCH] feat(ci): build the linux-arm64 native for the .NET and JVM
 bindings

The chat_xdk_dotnet cdylib ships for osx-arm64, osx-x64, linux-x64 and
win-x64, so the JVM and .NET bindings cannot run on 64-bit ARM Linux --
AWS Graviton, Ampere, and ARM CI runners. On Linux/aarch64 detectRid()
returns null, no bundled native is extracted, and the load falls through
to a system lookup that finds nothing.

The Python job already builds aarch64-unknown-linux-gnu on ubuntu-24.04-arm,
so the target and the runner are already proven here. Since dotnet-build
also feeds the java job, one matrix entry covers both bindings.

- add the linux-arm64 entry to the dotnet-build matrix
- stage it alongside the other RIDs for both the nupkg and the jar
- require it in the jar verification list
- return linux-arm64 from detectRid() on Linux/ARM
