[DOC] rancher2_config_map_v2 Import example contains an error

[ip025]

I found a copy/paste oversight in the documentation.

The import example for the rancher2_config_map_v2 resource seems to be copy/pasted from the rancher2_secret_v2 resource but not fully adapted.

it reads:

$ terraform import rancher2_config_map_v2.foo <CLUSTER_ID>.<SECRET_V2_NAMESPACE>/<SECRET_V2_NAME>

i guess it should read:

$ terraform import rancher2_config_map_v2.foo <CLUSTER_ID>.<CONFIG_MAP_V2_NAMESPACE>/<CONFIG_MAP_V2_NAME>
