Subject: [PATCH] Remove uniqueItems from blockStates schema

Ajv 6 checks uniqueItems on object arrays with a pairwise deep-equal loop,
which is O(n^2). blockStates.json files have ~17k entries, so each of the
29 bedrock versions took 12-36s to validate (~425s of a ~9min CI run);
the same file validates in ~11ms without it. Uniqueness of generated
block state entries is not an invariant we rely on.
