chore(deps): take utopia-php/query 0.7.1

#968 merged with a dev- pin on the feat-query-relationship-method split,
which disappears once that branch is deleted and blocks stable consumers.
0.7.1 is the tagged release of appwrite/appwrite#14502 and carries the
same Method::Relationship and Query::relationship() the nested
relationship queries need.
