Expected behavior

I don't expect AI zones to be returned.

Actual behavior

AI zones are returned.

Additional context

Documentation about AI Zones

The above says:

You must enable the --extraLocationTypes flag when using the locations.list API to ensure AI zones appear only to those who intend to use them.

The documentation for that new field says:

By default, omitting this field means only the generic Cloud locations will be returned in the response. The supported values are: "CLOUD_AI_ZONE"

This API should have similar default-opt-out functionality.
