Please use riscv64/ubuntu:26.04 because 26.04 is the latest LTS.

I have updated the docker run command to include the environment variable QEMU_CPU=rv64,v=on,vlen=128,vext_spec=v1.0, and verified that RVV is working correctly.
The vext_spec=v1.0 explicitly specifies the vector extension version to suppress the warning: "vector version is not specified, use the default value v1.0".
Set QEMU_CPU=rv64,v=on,vlen=128,vext_spec=v1.0 in the riscv64 CI job and pass it into the Docker container via -e QEMU_CPU. This ensures the emulated RISC-V CPU has the V extension enabled so that ORC's RVV code path can be exercised in CI.

What this PR does
Adds a RISC-V (riscv64) Docker image for Ubuntu 24.04 and wires it into GitHub Actions so we can continuously build ORC on RISC-V.
