[BUG] Failed to parse private key: Error: Only 8, 16, 24, or 32 bits supported: 528

I just used `firebase init hosting:github` to initialize the github action as I always do but after it compiles the code it gives this error.

### Error message

```
FirebaseAppError: Failed to parse private key: Error: Only 8, 16, 24, or 32 bits supported: 528
```

### Action config

```
- uses: FirebaseExtended/action-hosting-deploy@v0
