Pulling dependencies

[colin-morpho]

I noticed that in other Morpho projects it's possible to pull project dependencies using yarn, for instance. I think we could provide a package.json to ease out development and ensure reproducibility.

the reason why we use yarn on other project is because we use hardhat and thus we need the "js stack". Here the dependancies are only solidity ones, and we usually manage them using foundry's integrated package manager (which is actually git modules).

Ok, thank you for making that clear!
