I executed that persistence.xml and then the Hibernate show me this message

23:50:44.846 [main] WARN org.hibernate.orm.connections.pooling - HHH10001002: Using Hibernate built-in connection pool (not for production use!)
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Therefore, I recommend to change this to the under line

<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />

->

<property name="javax.persistence.jdbc.driver" value="com.mysql.cj.jdbc.Driver"/>
