Update GCE VM Instance example

[modular-magician]

This was changed in GoogleCloudPlatform/magic-modules#4113, but e2 vm instances can't use local ssds! This has been broken for years 🤯

service_account_id was also not a valid value, but changing the machine type broke it first. Added some slightly better prefilled values, although there are still numerous foobars kicking around.

As funny as updating a broken config with another broken config would be, works on my machine (tm):

Plan: 2 to add, 0 to change, 0 to destroy.
