feat(template): add overrideTemplate method && closed #54

This commit adds a new method `overrideTemplate` to the `TeamPromptsBuilder` class. This method allows retrieving an overridden template for a given filename. It first checks if there is an override template in the project's team prompts directory, and if found, returns the content of the override template. If no override template is found, it falls back to the default template. This method is useful for customizing templates on a per-project basis.
