Description

After editing an operation that's already implemented in an API Provider integration, there's no indication on the Operation List page that the flow needs to be updated.

Steps to reproduce

1. create an API Provider integration with a flow that requires a data mapping
2. edit the operation so that the data mapping would not be valid (e.g. change the return type)
3. save the API definition
4. no indication that the mapping is no longer valid
