Set the spring.jpa.database-platform to provide better log messages

[arueth]

Background

Log messages for DB related issues are not very helpful, an example:

buildNativeEntityManagerFactory | Failed to initialize JPA EntityManagerFactory: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] due to: Unable to determine Dialect without JDBC metadata (please set 'jakarta.persistence.jdbc.url' for common cases or 'hibernate.dialect' when a custom Dialect implementation must be provided)
refresh | Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] due to: Unable to determine Dialect without JDBC metadata (please set 'jakarta.persistence.jdbc.url' for common cases or 'hibernate.dialect' when a custom Dialect implementation must be provided)

Change Summary

Setting the spring.jpa.database-platform provides more useful log messages.

Caused by: org.springframework.orm.jpa.JpaSystemException: Unable to acquire JDBC Connection [FATAL: password authentication failed for user "admin"] [n/a]

Testing Procedure

Tested locally with skaffold and in my clusters
