Money class for Spring Boot 3

[kwonglau]

@cer, should we publish a new version of this dependency so that we can use in this branch https://github.com/eventuate-tram/eventuate-tram-sagas-examples-customers-and-orders/tree/wip-spring-boot-3

or should we copy the Money in the project and fix the following import ?

import javax.persistence.Access;
import javax.persistence.AccessType;
import javax.persistence.Embeddable;

[cer]

Such a PITA.

I'd add a eventuate-examples-common-money-jakarta9 module that's a copy of the existing one.
