Disallow deprecated entity attribute types

[njr-11]

It is best if Jakarta Data disallows the entity attributes that are deprecated by JPA 3.2 so that customers don't start using them only to later see them removed.

We had one test case that was using a deprecated type: java.sql.Timestamp
It was using it as a Version attribute, so I tried switching to java.time.LocalDateTime, which has a similar meaning and is listed as supported by JPA 3.2. EclipseLink rejected it, so I reported that to the JPA team and placed a TODO comment in the code pointing to the tracking issue and temporarily using Long instead.
