What does this PR do / why we need it:

An integration test is failing after registry is updated and the Go stack got a new version.

  to be equivalent to
      <string>: 2.0.0
  In [It] at: /go/src/github.com/redhat-developer/odo/tests/integration/cmd_devfile_init_test.go:187 @ 05/04/23 00:38:54.514

Instead of hardcoding the value of the latest version of the Go stack, the latest value is obtained by reading the index of the Devfile Registry.

Thank you fixing this!
There is one more test related to the JSON output that needs to be fixed though.

I think we can merge the changes from #6788 as well, use a dedicated versionCheck instead of gotLatest.
