chore: refactor Go projects and update CI configs

- Update Go versions in CI workflow to include 1.20, 1.21, and 1.22, and remove versions below 1.18
- Change directory structure for tests in `example36-performance` and `example52-ring-buffer-queue`
- Add `go.mod` file for `example36-performance` with Go version 1.21.4
- Create `go.mod` file for `example52-ring-buffer-queue` specifying Go version 1.21.4 and dependencies
- Introduce `go.sum` for `example52-ring-buffer-queue` with checksums for dependencies
