Fix type assignment in StrategyFactory for ImportableStrategyConfig

[rsmb7z]

Pull Request

This PR addresses a typing inconsistency observed in the ImportableStrategyConfig, a subclass of NautilusConfig. The core functionality expected from these configurations is the ability to be stored and parsed as JSON/YAML files. However, it was identified that while loading the strategy configurations as part of ImportableStrategyConfig, they were not receiving the correct type assignments.

To resolve this issue, the PR implements a fix ensuring that the strategy configuration is correctly parsed with appropriate types when creating strategies using StrategyFactory. This enhancement aligns ImportableStrategyConfig with the intended design of being fully compatible and operable with JSON/YAML file formats, thereby improving reliability and consistency in configuration handling.
