This test just:
* uninstalled bazel (if it was installed)
* installed bazel from the package you built
* asserted that the installation did not return an error exit code
* ran ``bazel version`` and asserted non-error exit code
* ran ``bazel info`` and asserted non-error exit code

The bazel commands should now be repeated in the other shells. Should work in:
* powershell (probably what you just ran this in)
* cmd
* msys2
