feat: add Maritalk model component (langflow-ai#2595)

* feat: add Maritalk icon

* feat: add Maritalk model component

* fix: update icon size

* feat: optimize MaritalkModelComponent initialization

This commit optimizes the initialization of the MaritalkModelComponent class in the Maritalk.py file. It updates the default value for the 'temperature' parameter to be within the range of 0 to 1, using the RangeSpec class. This ensures that the temperature value is valid and improves the overall functionality of the component.

* feat: update 'stream' parameter to be advanced in MaritalkModelComponent

This commit updates the 'stream' parameter in the MaritalkModelComponent class to be an advanced option. By setting the 'advanced' attribute to True, the 'stream' parameter will only be visible to advanced users. This change improves the usability of the component by hiding this option from regular users who do not need it.
