Added update action to change Input Hint on Attribute Definition

The inputHint on AttributeDefinition provides a hint to developers how text-based attribute values should be visually represented in the frontend. The two supported values for this field: SingleLine or MultiLine had to be set in the AttributeDefinitionDraft during creation of the attribute definition so far, but it can now be changed afterwards by introducing a new update action changing the value of this field.
