For specific LRU contexts (version, param, param_value), the Bicep LS was
appending its own random/irrelevant completions alongside the LRU catalog
items. The LS has no knowledge of the private ACR registry, so its suggestions
in these positions are noise.
Now the LS items are discarded entirely for these three contexts. LS items
are still kept (below LRU items) for module_path and unknown contexts.
