Fix: Add missing placeholder for TABLE_NAME in MariaDB table existence check

[91wangmeng]

Fix table existence check in MariaDBSchemaValidator

Issue:
The SQL query in the isTableExists method of MariaDBSchemaValidator class has a syntax error. The original query is missing a placeholder for TABLE_NAME, which results in an incomplete SQL statement and affects the table existence check functionality.

Changes:

• Added %s placeholder for TABLE_NAME in the SQL query
• Ensured String.format method correctly uses both schemaName and tableName parameters

This fix ensures the table existence check functionality works properly in the MariaDB vector store implementation.
