ci: update python in GHA for integration tests (#83)

I tried to sync this repo with latest API spec #82 and noticed that
integration tests fail because we need Python 3.10 for ansible
collection now
equinix/ansible-collection-equinix#155

This PR updates Python in the integration tests GHA to 3.10. i will
re-run the integration tests in #82 when we merge this.
