compute: make zone configurable on google_compute_future_reservation

[GitOleksandrBokov]

google_compute_future_reservation cannot be created: zone was declared as an output-only property, so the generated schema rejects any configured value (Can't configure a value for "zone"), while the create URL (projects/{{project}}/zones/{{zone}}/futureReservations) still requires it and fails with Cannot determine zone unless a provider-level zone is set.

This PR declares zone as an optional immutable parameter with a provider-level fallback, following the compute.Disk / compute.Reservation pattern. The generated schema becomes Optional + Computed + ForceNew with self-link diff suppression, so both a zone name and a zone URL are accepted without a permadiff.

Verified against the regenerated google-beta provider:

• terraform plan with zone set on the resource succeeds (previously failed at plan time).
• terraform apply builds the request URL from the configured zone.
• Provider schema validation (TestProvider) and compute unit tests pass.
• Requests without zone in config are unchanged (still resolved from the provider zone), so existing VCR cassettes stay valid.

compute: fixed `zone` field being output-only in `google_compute_future_reservation`, which made the resource impossible to create without a provider-level zone
