Fix linter errors in Go SDK BUILD.md and README.md files (#32658)

 changes and execute tests from within the module directory (`<repo>/sdks/...`).
 
 Go users can just `go get` the code directly. For example:
-```

 go get github.com/apache/beam/sdks/v2/go/pkg/beam

 Developers must invoke Go for cross-compilation manually, if desired.
 
 If you make changes to .proto files, you will need to rebuild the generated code.
 Consult `pkg/beam/model/PROTOBUF.md`.
 
 If you make changes to .tmpl files, then add the specialize tool to your path.
 You can install specialize using:
-```
+
+```bash
 go get github.com/apache/beam/sdks/v2/go/cmd/specialize
 ```
+
 Add it to your path:
-```

+```bash
 export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
