Subject: [PATCH] Move the conversation renderer to Horizon 88e0110

The Prompt tab's What it added mode said the request before was not among
the loaded bodies whenever it had nothing to compare with. For every
LangChain call, and for the first call of any chain, the request names no
request before it, so nothing was missing. Horizon's renderer now says the
request names none before it (apache/skywalking-horizon-ui#173), and the
embedded copy moves to that commit.
