Use PATCH instead of PUT in data provider

**Issuel**
In the data provider, we currently use a PUT request to update data. The problem is that if two people update the same data, there's a risk that one person's update will be overwritten by the other's update.

**Proposal**
Just as, on the middleware side, we now do https://github.com/assemblee-virtuelle/semapps/pull/664 a diff to update data, we could do a diff on the frontend that would allow PATCH requests rather than PUT.

> See if we can mutualize code between middleware and frontend.

**Components concerned**
Semantic data provider

Start with the Semantic data provider and compare its current PUT update flow with the middleware diff approach referenced in pull request 664. Investigate whether the diff logic can be shared between the frontend and middleware; done means updates use PATCH without overwriting unrelated concurrent changes.
