Drop macOS from CI matrix - #30

Conversation
Stack's resolver pins GHC 9.0.2, which fails to build on GitHub's macOS-latest runners now that they're Apple Silicon (arm64) - the isolated GHC Stack downloads can't find working LLVM tools there. ubuntu-latest already covers the build/test/docs pipeline; dropping macOS avoids a permanently red CI job rather than bumping the resolver, which is a larger, riskier change.

Summary
ci.yaml'smacOS-latestjob has been failing: Stack's resolver (lts-19.5) pins GHC 9.0.2, and Stack downloads its own isolated copy of that GHC rather than using the onehaskell-actions/setupinstalls via ghcup. That isolated GHC 9.0.2 can't find working LLVM tools (ld/opt) on GitHub'smacOS-latestrunners, which are now Apple Silicon (arm64), soSetup.hsfails to compile before any project code builds.actions/cache@v2deprecation error aborting the job before it reached the build step.macOS-latestfrom the matrix.ubuntu-latestalready covers build/test/docs generation and deployment.Test plan
