Bug 31925: Document that thesaurus-aware linking depends on index freshness
QA (comment 58/60) suggested LinkerConsiderThesaurus only works with
Elasticsearch, having observed duplicate authorities being created when
testing with Zebra. Reproduced this directly: with AutoCreateAuthorities
and LinkerConsiderThesaurus on, saving two bibs with the same new FAST
heading back-to-back (no pause) creates a duplicate authority under
Zebra, but waiting for Zebra's indexing daemon to catch up (a few
seconds) between saves lets the second heading link to the first-created
authority correctly, as designed.

The same duplicate-on-rapid-succession behaviour also reproduces with
LinkerConsiderThesaurus off and a plain LCSH heading - it's a pre-existing
race between AutoCreateAuthorities and Zebra's asynchronous indexing
daemon, not something specific to thesaurus-aware matching or this bug.
Elasticsearch indexes near-synchronously within the same request, so the
same race window is far less likely to be hit there, which is almost
certainly why this only showed up in manual Zebra testing.

This documents that dependency on the LinkerConsiderThesaurus system
preference description, rather than gating the feature to Elasticsearch
only, since the underlying logic is search-engine agnostic and works
correctly on Zebra given normal indexing latency.
