Create tutorials in each SDK walking through how their respective travel sample application works.

Add a full walkthrough for the backend of the travel sample application for each of the SDKs. These walkthroughs will need to cover the following general points:

• How to install and run the travel sample app (this already exists in most SDK docs)
• An introduction to the app and the features it offers.
• A brief overview of the frontend, notably how it requests data from the backend
• A section giving a full walkthrough each of the API endpoints implemented by the backend. This should be done in a buildup format, introducing K/V, Query, then Search, to show how each service can be utilised for the different use cases needed by the frontend.

Note the page URL given is for the Python SDK as that is the default backend
