This change updates SqlDialectLookup to delegate to jOOQ's JDBCUtils
rather than creating an additional mapping between
org.springframework.boot.jdbc.DatabaseDriver and org.jooq.SQLDialect.
This has the following advantages:
1. jOOQ's `SQLDialect` to URL mappings are already maintained by jOOQ,
so no additional changes will be necessary to Spring Boot in the
future.
2. Delegating to jOOQ means that the mapping also works for the
commercial jOOQ distributions, e.g. when working with DB2, Oracle,
SQL Server, etc., as the JDBCUtils of the commercial distribution
also contains the relevant logic to map to e.g. `SQLDialect.DB2`,
`SQLDialect.ORACLE`, `SQLDialect.SQLSERVER` (which are not
available from the open source distribution linked by Spring Boot
by default).
