Add details about launching apps with uri_data

Example: https://docs.google.com/spreadsheets/d/1hep9Ibtd2u3rtPviNn8HS0qbwjGoJy4JtZOn6xdHkMk/edit#gid=0

Need to build dynamic params: https://forum.getodk.org/t/not-able-to-use-dynamic-data-in-intent-expression-and-well-as-for-url/43391/4?u=ln

Start by locating the existing documentation for uri_data, then review the linked Google Sheets example and forum discussion about dynamic parameters. Done means the documentation explains how to launch apps with uri_data and how to build dynamic parameters, with a usable example.
