doc: Fix typo in rule-system view example

Commit dcb00495236 accidentally changed the final expanded query's
condition to > 2 while rewriting the example into SQL operator notation.

The original query and the preceding rewritten forms all use >= 2,
and view expansion should preserve that qualification. This commit
changes the final condition from > 2 to >= 2.

Backpatch to all supported versions.
