* fix(compute-vm): prevent instance recreation for key_revocation_action_type
The `key_revocation_action_type` attribute in the `google_compute_instance`
resource defaults to `NONE` on the provider side.
When this optional attribute was not explicitly set in the module's
`options` variable, it resolved to `null` in the Terraform configuration.
This caused Terraform to detect a change from `null` to `NONE` on every
plan, leading to unnecessary instance recreation.
This change applies `coalesce` to
`var.options.key_revocation_action_type` in the resource definition so
that it defaults to `NONE` when unset, aligning the configuration with
provider behavior and preventing a permadiff.
* updated the regional compute template too with the key_revocation_action_type
* fixed the formatting
