### What problem does this PR solve? Problem Summary: https://github.com/microsoft/mssql-jdbc/blob/v13.4.0/src/main/java/com/microsoft/sqlserver/jdbc/SQLServerDatabaseMetaData.java#L1887-L1934 ``` SQLServer JDBC catalog lists schemas through DatabaseMetaData.getSchemas(conn.getCatalog(), null). With mssql-jdbc 13.4.x, when catalog is non-empty and schemaPattern is null, the driver filters built-in schemas such as dbo, guest, sys, INFORMATION_SCHEMA, and db_*. As a result, SHOW DATABASES on a SQLServer JDBC catalog may miss schemas that were visible with older mssql-jdbc versions. Now SQLServer-specific override for schema discovery and passes schemaPattern % to getSchemas. % is the JDBC wildcard pattern for matching all schemas, so mssql-jdbc 13.4.x returns the expected schemas without the driver-side built-in schema filtering. Older mssql-jdbc versions are also compatible with this behavior. ``` ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [x] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
