refactor(presets): add nu scripts support

What

This MR add support for nushell scripts in presets.

Why

For more complex tasks, we have commands that are way too long, we need a more maintainable way to do this !

How

Add nu scripts in resources folder and import them with the config module. Then we need to execute them in the presets by just passing them the templated args

Closes #17 (closed)
