Detect JSON path bug in MariaDB

MariaDB > 10.9.2 has a bug in JSON path handling which considers a '-' character in a quoted member name as a syntax error.

This ticket proposes to detect this bug in isJsonSupported and to fix all unit tests depending on json_extract but failing to test if JSON is supported.
