Requesting a pod for cpu via python sdk seems not possible

[Lhemamou]

Describe the bug
When I want to create a only cpu pod, it's needed to choose a gpu_type_id but when i test all the gpu_type_id with gpu_count=0 , I have not access to any server.

To Reproduce
`list_gpus=[x['id'] for x in runpod.get_gpus()]

for gpu in list_gpus:
try:
runpod.create_pod(name="test_pod",image_name="docker/image",
gpu_count=0,gpu_type_id=gpu,
container_disk_in_gb=20,
min_vcpu_count=2,min_memory_in_gb=8,ports="8080/http;22/tcp")
break
except runpod.error.QueryError as e:
print(e)`

-> print statement :
There are no longer any instances available with the requested specifications. Please refresh and try again.
