Setup the PUT endpoint for nomenclatures

[julbrs]

Actually there is no PUT endpoint to update the nomenclature entity.

The swagger documentation is already partially written.

The goal of this endpoint:

• be able to update the fields of the nomenclature
• it will take as input the id of nomenclature
• we just want to update for the moment the following fields:
  • name (name of nomenclature)
  • cards.originalname (the name of each card)
• we don't want to be able to update the image associated to each card (for the moment)
