`failed to bring up tailscale: starting tailscaled failed: exec: "tailscaled": executable file not found in $PATH` when deploying container to Google Cloud Run

### What is the issue?

The docker run cmd works but deploying `` to google cloud run will fail with log saying
```
2024-02-21 20:36:41.548 EST
boot: 2024/02/22 01:36:41 Starting tailscaled
2024-02-21 20:36:41.548 EST
boot: 2024/02/22 01:36:41 failed to bring up tailscale: starting tailscaled failed: exec: "tailscaled": executable file not found in $PATH
2024-02-21 20:36:42.453 EST
Container called exit(1).
```

### Steps to reproduce

use image `tailscale/tailscale:latest` in cloud run. Is there anything missing given the error? I'm new to cloud run but have deployed a few other docker containers from docker hub without any issue.
