What

Increase the disk to the provisioned VMs.

Why

When using test networks such as ghostnet, this is necessary (default is 5GiB).

How

Increase the size to 200GiB. This is still hard-coded. We can consider later on to parameterise this value if necessary.

Cost why, this should remain cheap since the charge for such a disk is $48 for an entire month (so a bit more than a $1 per day).

Manually testing the MR

dune exec tezt/tests/cloud/main.exe -- cloud health -v

should work.
