fix: json numeric filter

[Weakky]

Overview

• fixes JSON number filtering bug prisma#8224 (Postgres JSON numeric comparisons)
• fixes MySQL and MariaDB JSON numeric comparisons too (fix(mysql): numeric comparison with json_extract quaint#310, fix(mysql): json numeric comparisons on both sides quaint#311, fix(mariadb): json gt/gte/lt/lte comparisons quaint#315)
• have JSON filter tests actually run again

Deeper dive

• On Postgres, we were applying ASCII comparison instead of numeric comparison
• On MySQL and MariaDB, we're doing the comparisons against the deserialized json values
