commcare: add examples

[aleksa-krolls]

Ideally we should have at least 2-3 basic examples for all adaptors, like we do with DHIS2.
https://docs.openfn.org/adaptors/library/jobs/auto/DHIS2-DataValues-API

Can you please add a couple of examples for commcare? Make sure these examples DO NOT contain PII, nor client data. Examples can be added to docs here: https://github.com/OpenFn/docs/tree/main/adaptors/library/jobs
