Add SimplifyJacksonExceptionCatch recipe

[timtebeek]

Summary

• Adds a new recipe SimplifyJacksonExceptionCatch that simplifies multi-catch clauses where Jackson exceptions are caught alongside RuntimeException
• In Jackson 3, JacksonException and its subtypes extend RuntimeException, making it redundant to catch both
• Handles all Jackson 3 exception types: JacksonException, StreamReadException, StreamWriteException, UnexpectedEndOfInputException, and DatabindException
• Removes unnecessary imports for the removed exception types

Example

// Before
try {
    mapper.readValue(json, MyClass.class);
} catch (JacksonException | RuntimeException e) {
    e.printStackTrace();
}

// After  
try {
    mapper.readValue(json, MyClass.class);
} catch (RuntimeException e) {
    e.printStackTrace();
}

Test plan

• Added comprehensive tests covering basic simplification, subtype handling, multiple exceptions, preserving other types, and no-change scenarios
• All tests pass locally
