URL: https://github.com/apache/airflow/issues/55571
### Apache Airflow version
main (development)
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
```javascript
pt/airflow/airflow-core/src/airflow/api_fastapi/core_api/routes/public/plugins.py",
line 47, in get_plugins
return PluginCollectionResponse(
File "/usr/python/lib/python3.10/site-packages/pydantic/main.py", line
253, in __init__
validated_self = self.__pydantic_validator__.validate_python(data,
self_instance=self)
pydantic_core._pydantic_core.ValidationError: 1 validation error for
PluginCollectionResponse
plugins.16.external_views.0.destination
Input should be 'nav', 'dag', 'dag_run', 'task' or 'task_instance'

/>
### What you think should happen instead?
The error makes sense that its user mistake but other plugins should still
work.
### How to reproduce
Try to register below plugin:
```python
from airflow.plugins_manager import AirflowPlugin
external_view1 = {
"name": "Airflow Croma",
"href": "http://localhost:28080/dags/access_control";,
"destination": "Assets",
"icon": "book",
"url_route": "my_external_view",
# "category": "browse"
}
# Defining the plugin class
class AirflowTestPlugin2(AirflowPlugin):
name = "test_plugin2"
external_views = [external_view1]
```
