Enable FalkorDB fulltext search tests

Testing revealed that all FalkorDB fulltext search tests pass successfully.
The skip was added in PR #872 without explanation and appears to be unnecessary.
Removed FalkorDB from the skip conditions, keeping only Kuzu skipped (which
legitimately doesn't support dynamic fulltext index creation).

Tests verified passing locally with FalkorDB 1.2.3.
