tofu: refresh network name

[aborrero]

The network has a new name.

Bug: T389942

did you check whether tofu lets this to be changed without re-creating things? this variable is directly fed to the openstack_containerinfra_clustertemplate_v1 resource (without being translated to an ID first)

also, fixed_subnet below is not changing, right?

The change is unlikely to require re-creating, as the ID of the network has not changed. The network name is usually a cosmetic thing. This did not require re-creation even in the tofu-infra repository.

In any case I have to say: I did not checked, and I don't plan to. Whoever wants to follow up merging this patch will need to double check.

Correct, this is not changing.
