feat!: Send X-Asset-Ingested header for update/create of value and resources (DEV-2628)

This represents a breaking change in the sense that when using the dsp-js-lib the asset upload must be done using dsp-ingest and cannot be done using Sipi anymore.

The changes look reasonable, but I do not know JS-LIB at all, so I wouldn't know if the present changes are sufficient

Ok for me, just, as a side note using constants would be beneficial in order to decrease repetitive code.

Good point. I would prefer that as well. Unfortunately I have not been able to add it to the Constants.ts, import and use it as the key for the headerOpts object. Keeps complaining that the string is not a RecursiveString something.

Next time maybe?
