create rubocop that will check location of FactoryBot file for specific model

[Ivanov-Anton]

To improve the consistency of factory definitions, we can add a separate Rubocop rule, such as FactoryBot/LocationPath, that enforces creating FactoryBot files in the appropriate folder based on the namespace of the corresponding model.

For instance, if we have a model named "Main::Chat," in the case when the developer defines each factory as a separate file, the FactoryBot file should be located under the "spec/factories/main/" folder.

By implementing this Rubocop rule, we ensure that all factories are consistently organized and adhere to the correct naming conventions and directory structure.
