fix: remove version_added in gcp_compute

The version_added field is documented for a very small set of
fields, specifically in gcp_compute today.

Removing these values as they are specifying the ansible-core version
which is confusing for those who are installing via ansible-galaxy,
and the value is not set for any other module.

fixes #550.
