doc issue: "subnets doc" missing

[clnperez]

https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/resources/compute_vm_instance#public_subnet and https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/resources/compute_vm_instance#private_subnet

both contain a dead link instead of documentation about the subnets.

Without a link to this I can't tell what kind of value I should pass in for the subnet.

The links above is not releated to the documentation...It takes you to the list of subnets in your account

Then I think the wording needs some clarification. It says "You can find accepted values in the subnets doc, Note You can see the list of private subnets of your account."

subnets doc to me sounds like it should point to documentation. More clear would be something like,

Acceptable inputs for this field are any of the names of an existing subnet from your account. You can find these names here: [account subnets](https://cloud.ibm.com/classic/network/subnets).
