Enhance the tech_review hook

### 📝 Description of the feature

Use the [docstring parser](https://pypi.org/project/docstring_parser/) to check docstrings in repositories are valid/compliant as suggested by @AlejandroFernandezLuces

Perhaps we can make this a new hook or add it to the tech_review hook

### 💡 Steps for implementing the feature

- Look through each python file in certain directories & parse the docstrings in each function and/or class
