Cookbook for better Redocly CLI recipes

Redocly CLI offers extensive configurability, allowing users to customize their API pipelines through an open-source cookbook available on GitHub, which provides a collection of extensions and configurations. This resource is designed to support both expert users and those less familiar with coding by offering a variety of "recipes" or examples that can be adjusted to fit specific needs. The cookbook encourages community involvement by inviting users to share their own tips and innovations, thereby enriching the repository with diverse solutions and fostering a collaborative environment. Users are encouraged to contribute their examples, explore existing ones, and request new features by interacting with open issues, promoting an ongoing exchange of ideas and enhancements within the Redocly CLI community.
