Adding cache.key to eas.json after SDK41 migration

Hi @adamjnav

Thanks for the reply, I’ve actually starting using the syntax you have suggested in other projects.

Some times that solves the issues if it is related to cache problems, other times as the error message suggest can be related to conflict of dependencies.

As matter of curiosity, my understanding is that the cache issue should be now solved by PR341 as stated by @charliecruzan here Expo SDK 41 EAS build failing - #7 by charliecruzan

Cheers
