Refactor CI workflow and Makefile

The changes in this commit refactor the CI workflow and Makefile. Specifically, the changes include:

- Updated the workflow file `.github/workflows/ci.yml`:
  - Replaced the `go-version` with `1.21.x` in the `strategy.matrix` section.
  - Updated the `actions/setup-go` to version 4.
  - Changed the build command to `make callhome`.
  - Added a step to run tests using `make test`.

- Updated the `Makefile`:
  - Added a `test` target to run tests with verbose output, race detection, and atomic coverage.
