Add a field for metadata modification date #218

While the usage of dct:modified has been discussed and perfected (https://github.com/opendata-swiss/dcat_ap_ch/issues/179), and will be made easier to use and understand by the inclusion of DatasetSeries, I would suggest that we could include a separated optional field for the metadata modification date

Modifications to the data: dct:modified
Modifications to the metadata: dct:modified_metadata (or other name). This will allow to see when there are modification to the description, publisher, ... of the data, without affecting the data itself

I'm not sure this is needed (see my comment in https://github.com/opendata-swiss/dcat_ap_ch/issues/179#issuecomment-2173370922).

How could a consumer of this information benefit from this change?

@metaodi I added the suggestion after rather long discussions on this topic. Some in our group thought that if you correct a spelling mistake in the dataset description, the dct:modified should not be updated, since the change is basically not relevant and should not trigger updates or new analyses, but it is hard to say which are relevant changes and which are not. With this, it would become clear if you need to update your analysis (because the data is updated) or not (because only metadata was modified), while still keeping track of the metadata updates as well.
