dag.create_dagrun can raise `ParamValidationError`. We should capture it
when manually triggering a dag to avoid breaking the UI
Before:

```log
Something bad has happened.
Airflow is used by many users, and it is very likely that others had similar
problems and you can easily find
a solution to your problem.
Consider following these steps:
* gather the relevant information (detailed logs with errors, reproduction
steps, details of your deployment)
* find similar issues using:
* [GitHub Discussions](https://github.com/apache/airflow/discussions)
* [GitHub Issues](https://github.com/apache/airflow/issues)
* [Stack Overflow](https://stackoverflow.com/questions/tagged/airflow)
* the usual search engine you use on a daily basis
* if you run Airflow on a Managed Service, consider opening an issue using
the service support channels
* if you tried and have difficulty with diagnosing and fixing the problem
yourself, consider creating a [bug
report](https://github.com/apache/airflow/issues/new/choose).
Make sure however, to include all relevant details and results of your
investigation so far.
