ci: adjust storage requests

Makes two changes to the PVCs:

  * preview 50G -> 20G
  * testnet 200G -> 300G

We don't need 50GB of storage per node on preview. That's >2 weeks
runtime, and we've never gone >2 weeks without deploying to preview.
For testnet, though, we grow the storage requests: 200GB is roughly ten
weeks, and we're approaching full utilization on Testnet 64 already.

We can still adjust these storage requests over time, but updating them
now to reflect our expectations.
