Missing references to some nightly compilers

* [ ] `/opt/compiler-explorer/llvm-mos-trunk/bin/clang` - this is because we point to the various symlinks
* [ ] `/opt/compiler-explorer/bpf/gcc-trunk/bpf-unknown-none/bin/bpf-unknown-g++`
* [ ] `/opt/compiler-explorer/carbon-trunk/bin/carbon-explorer`
* [ ] `/opt/compiler-explorer/cobol/gcc-cobol-master/bin/gcobol`
* [ ] `/opt/compiler-explorer/dotnet-trunk/.dotnet/dotnet` - this might be because we use specific executables for the various languages
* [ ] `/opt/compiler-explorer/hook/hook-0.1.0/bin/hook`
* [x] `/opt/compiler-explorer/SPIRV-Tools-master/build/tools/spirv-dis` - we use this, but don't have it as a compiler, so this is expected
* [x] `/opt/compiler-explorer/llvm-spirv-trunk/bin/llvm-spirv` - same, not a compiler
* [x] `/opt/compiler-explorer/swift-5.10/usr/bin/swiftc` - fixed with https://github.com/compiler-explorer/compiler-explorer/commit/e45ba2d0892b45b3534937d4394ed5ef49441f86

Use the six unchecked compiler paths as the checklist and locate the repository configuration that records compiler references. The work is done when each unchecked path is either included or explicitly accounted for, while the two checked non-compiler tools remain unchanged.
