[Documentation] OGC Documentation Enhancements

[LucaCinquini]

PM Ticket Reference: unity-sds/unity-project-management#208

Description:

-Documentation on assumptions/requirement of Airflow DAG input parameters
-Best Practices
-Reference the existing OGC API notebook to gitbook? Need to capture detailed explanations on what we have in this notebook (https://github.com/unity-sds/unity-monorepo/blob/156153922a00d38fc0c8486a79a7627916d51c30/libs/unity-py/notebooks/ogc_notebook.ipynb)

Acceptance Criteria:

• Overview of OGC Processing: Provide an overview of the OGC processing, including the OGC standard/specification.

• Best Practices: Document best practices for using the Airflow OGC API and DAG effectively, and highlight common user confusions or mistakes. (future) Consider including best practices for writing DAGs for capturing airflow processing metrics.

• Examples: Offer multiple examples demonstrating the OGC processing in various scenarios, with step-by-step procedures and accompanying screenshots or diagrams where applicable. Reference the existing OGC API notebook. (Drew already put together notebooks and request ASIPS review for what's missing)
