get first repo with todos
Created by: unclejustin
Closes https://github.com/sourcegraph/sourcegraph/issues/30745
Updates the dynamic example to check for an actual repo with TODOs. If no repo is found containing "TODO" then the first repo is used.
Note: We are assuming that all customers will have at least 1 repo. In the unlikely event that no repo is found then an empty string will be returned.
