Unmaintained collection: Removal from Ansible (communtiy) package

It looks like this collection is effectively unmaintained. According to the current [community guidelines for collections](https://github.com/ansible-collections/overview/blob/main/removal_from_ansible.rst#unmaintained-collections), we will consider removing it in a future version of the Ansible community package. Please see [Unmaintained collection: google.cloud](https://github.com/ansible-community/community-topics/issues/105) for more information.

At least one month after this announcement appears here and on [Bullhorn](https://github.com/ansible/community/wiki/News#the-bullhorn), the Ansible community engineering steering committee will vote on whether this collection is considered unmaintained and will be removed, or whether it will be kept. If it will be removed, this will happen earliest in Ansible 8.0.0. Please note that people can still manually install the collection with `ansible-galaxy collection install google.cloud` even when it has been removed from Ansible.

Read the linked removal_from_ansible.rst collection guidelines and the referenced community-topics issue 105 first. Follow the announcement on Bullhorn and wait for the Ansible community engineering steering committee vote; done means the collection is either retained or removed from a future Ansible community package release.
