Update CESS.md

Project Abstract

Updated the content in milestone 2, that is, replaced the CESS Contract of the storage mining module with Substrate Pallet. The reasons are as follows:

1. In view of the fact that the file processing module and the miner registration module in the project are implemented by pallet as shown in milestone 1, and the storage mining also needs to exchange information with the other two modules. Therefore, naturally we think that using pallet to build the storage mining module will make the project better.
2. From a design perspective, as a project of storage blockchain, the storage mining module should be the core part of the bottom layer. Therefore, implementing this as a pallet will be a better choice than as a smart contract.

Thanks alot for creating the PR. However, could you just change the few lines in the original file instead of changing the entire file as part of your PR. This way everyone immediately sees the difference and sees what actually has changed.
