## What changes were proposed in this pull request? This pr proposes to be case insensitive when matching dialects via jdbc url prefix. When I use jdbc url such as: ```jdbc: MySQL://localhost/db``` to query data through sparksql, the result is wrong, but MySQL supports such url writing. because sparksql matches MySQLDialect by prefix ```jdbc:mysql```, so ```jdbc: MySQL``` is not matched with the correct dialect. Therefore, it should be case insensitive when identifying the corresponding dialect through jdbc url https://issues.apache.org/jira/browse/SPARK-28552 ## How was this patch tested? UT. Closes #25287 from teeyog/sql_dialect.
