Pass SUBNET URL to console (#18503)

When minio runs with MINIO_CI_CD=on, it is expected to communicate
with the locally running SUBNET. This is happening in the case of MinIO
via call home functionality. However, the subnet-related functionality inside the
console continues to talk to the SUBNET production URL. Because of this,
the console cannot be tested with a locally running SUBNET.

Set the env variable CONSOLE_SUBNET_URL correctly in such cases. 
(The console already has code to use the value of this variable
as the subnet URL)
