bug: misguiding documentation for setting preferred factory functions

[patryk-kowalski-ds]

What happened?

https://ragbits.deepsense.ai/how-to/core/component_preferrences/#llm-configuration

The example setting for llm factory (text = "my_project.get_text_llm") suggests the function (pythonpath) should be linked by dots, while it needs a colon before function name to work with ragbits (like described in the docstring of subclass_by_factory - factory_path: A string representing the path to the factory in the format of "module.submodule:factory_name".)

Suggestion - just fix the examples to my_project:get_text_llm

How can we reproduce it?
