HLRC: Documentation examples cleanup (#34009)

* Replace deprecated field `code` with `source` for stored scripts (#25127)
* Replace examples using the deprecated endpoint `{index}/{type}/_search`
with `{index}/_search` (#29468)
* Use a system property to avoid deprecation warnings after the Update
Scripts have been moved to their own context (#32096)
