ci: refactor CI workflows and update actions

- Update GitHub Actions to use newer versions (checkout to v4, codeql-action to v3, setup-go to v5, goreleaser-action to v5, golangci-lint-action to v4, codecov-action to v4)
- Remove specific Go version pinning in favor of using the version specified in go.mod
- Enable checking for the latest Go version in setup-go action
- Replace `release --rm-dist` argument with `release --clean` in goreleaser action
- Reorder steps and remove redundant checkout step in testing workflow
