fix(ci): disable arm64 build (#913)

The arm-hooray runner seems to be missing causing the arm64 workflow to
time out. Hyperion does not have architecture-specific code, so the
arm64 build is not necessary because the program will likely compile on
arm64 if compilation succeeds on other architectures.
