fix: Add counter to onError trigger to break possible loops

[ceciliaavila]

#minor

Description

This PR adds a counter in the loop that executes the onError trigger to detect and break possible infinite loops when there's an error inside the onError handler.
It also includes a new property to the onError, to make the limit of executions configurable for the users (default value: 10).

Specific Changes

• Added executionLimit property to the onError trigger and read it in the override of the execute method.
• Updated internalRun method in DialogHelper to evaluate the execution limit property and break the loop in case of detecting one.
• Added executionLimit property to TurnPath to be able to store the value in memory.
• Updated Microsoft.OnError.schema and Microsoft.OnError.uischema to include the new property.
• Added 2 unit tests in conditional.tests to cover the new functionality.

Testing

These images show the scenarios we tested with the new implementation.
