Added the Joule unit "J" in CapacityUnitEnum

[LuciaCortesTH]

Background

In has been seen that in the ExternalUnitOfMeasure1Code from the 2Q2024 ISO External CodeSets v1, the unity Joule is supported in the Enum. However, in CDM this is not the case, as it does not appear anywhere in the CapacityUnitEnum.

Proposal

We believe that for completeness and to align with the 2Q2024 ISO External CodeSets v1, it should be included in the CapacityUnitEnum like this:

This proposal was approved in the APAC/JFSA DRR Peer Review.

Compatibility

Since this contribution would just include a new function in CDM, there are no issues with compatibility.

In DRR, as this value is required in version 5, we need to apply the changes in CDM 5. Aditionally we will contribute it to CDM version 6 to keep it updated with version 5.
