Update quota management API group version to v1alpha1

[astefanutti]

WHY

Quota management API in the quota.codeflare.dev group are currently versioned as v1. However these API are still to be hardened so it's better to versioned them as pre GA, and follow Kubernetes API lifecycle policy.

WHAT

Change the version of the APIs in the quota.codeflare.dev group to v1alpha1.
