Environment

```text
Jenkins: 2.387.2
OS: Linux - 5.14.0-162.18.1.el9_1.cloud.x86_64
Java: 11.0.19 - Red Hat, Inc. (OpenJDK 64-Bit Server VM)

```

### What Operating System are you using (both controller, and any agents involved in the problem)?

Linux jenkins 5.14.0-162.18.1.el9_1.cloud.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Mar 1 19:45:58 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

### Reproduction steps

Configure google-cloud vm with
1. One-Shot enabled
2. Create snapshot enabled
3. Location "europe-west3"
4. Zone "europe-west3-a"

Corresponding google project configured with "constraints/gcp.resourceLocations" set to
europe-west3-b
europe-west3-a
europe-west3
europe-west3-locations
europe-west3-c

Run a failing jenkins job e.g. "Simple Shell" with just "exit 1"

### Expected Results

Snapshot being created in the same region as the VM was running.

### Actual Results

Snapshot creation fails due to multi-region "EU" being used.
