Remove serializable for records one QuarkusTest does not require them

[magicDGS]

On #132, we discovered that records required to be serializable to work with quarkus-tests. This is already reported to quarkus for a long time (see quarkusio/quarkus#15892), but looks like no move have been done in that regard.

We should keep this issue open to simplify our code and remove the serializable class for our enums, as this is a requirement for test-only and should not leak into our actual code.

This is already fixed in Quarkus, although not releas is yet done for it. We should keep an eye on it.

Looks like it will be present in quarkus-3.12 (currently only on 3.11). Let's wait to upgrade when it is released

Still in 3.12.1 is not fixed, as the change to JBoss Marshalling was reverted. I added a comment into the original issue and I will open it again if it is not re-open.
