Switch build artifact to a default clang build. Testing with the build artifact locally, `make test` is failing with `/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.29' not found`. Using the gcc-11 build (might be?) installing GLIBCXX_3.4.29 but not linking it into the build. Rather than trying to get it to link, just use the pre-installed `clang` instead.
