fix: fix description of the injection token PROPAGATE_ERROR_TO_SERVER (#20107)

Aligned the injection token's description it with the real injection token name. 

The previous name-vs-description mismatch was misleading and caused harder troubleshooting when an error happened:
```
Internal server error: NullInjectorError: No provider for InjectionToken PROPAGATE_ERROR_RESPONSE!
```
It was hard to search/find it in the codebase, because there is no such injection token like `PROPAGATE_ERROR_RESPONSE`, but only `PROPAGATE_ERROR_TO_SERVER`.
