Update the hardhat version to v3

[kpachhai]

Problem

Currently, if I were to setup a hardhat v3 project and tried installing @hashgraph/system-contracts-forking, I get error:

>> npm install --save-dev @hashgraph/system-contracts-forking        
npm error code ERESOLVE
npm error ERESOLVE unable to resolve dependency tree
npm error
npm error While resolving: tutorial-hedera-fork-hardhat@1.0.0
npm error Found: hardhat@3.1.2
npm error node_modules/hardhat
npm error   dev hardhat@"^3.1.2" from the root project
npm error
npm error Could not resolve dependency:

npm error node_modules/@hashgraph/system-contracts-forking

npm error
npm error Fix the upstream dependency conflict, or retry
npm error this command with --force or --legacy-peer-deps
npm error to accept an incorrect (and potentially broken) dependency resolution.

Solution

Since Hardhat V3 is production ready and most users when setting up a new project end up using hardhat v3, I think it makes sense for us to support the plugin compatible with v3. Foundry works nicely.
