docs: update vector search filtering to reflect primary key support only

Browse Source 
Remove outdated references to filtering on columns provided in the
index definition, and remove the note about equal relations (= and IN)
being the only supported operations. Vector search filtering currently
supports WHERE clauses on primary key columns only.

Other filtering scenarios are currently not supported.
