- add openSUSE15.6 build configuration for qtopenapi.
- add rhel9.4 build configuration for qtopenapi.
- delete macos15-x86_64 build configuration for qtopenapi,
because the current qtopenapi code only builds go binaries
targeting arm64 architecture, and the x86_64 configuration would
fail trying to run those binaries.
