chore(deps-dev): bump hardhat from 2.0.11 to 2.4.1

[dependabot]

Bumps hardhat from 2.0.11 to 2.4.1.

Release notes

Sourced from hardhat's releases.

Hardhat v2.4.1

This release removes the warning shown by Hardhat when Solidity 0.8.x is used. Keep in mind that we currently support Solidity versions up to 0.8.4. Check the Solidity Support section of our docs to learn more.

Hardhat v2.4.0

This release adds support for Solidity 0.8.x, as well as multiple new features for customizing the behavior of the Hardhat Network.

New error messages

Some error messages returned by Hardhat have changed. If you have tests that check the exact message of a Hardhat error, you may need to update them.

For example, before this release a require(false, "this is the reason") statement would've generated this error message:

Error: VM Exception while processing transaction: revert this is the reason

In this new version, the error message will be:

Error: VM Exception while processing transaction: reverted with reason string 'this is the reason'

You'll also get different error messages for panic errors (for example, if you are using solidity 0.8.0 and divide by zero) and for custom errors. See below to learn more about these new features.

New supported solidity features

Custom errors

Hardhat now recognizes custom errors. For example, given this contract:

contract Foo {
  error MyCustomError(uint code, string message);
function test() public {
revert MyCustomError(42, "failed for some reason");
}
}

If you deploy Foo and call its test method, you'll now get a stack trace like this:

Error: VM Exception while processing transaction: reverted with custom error 'MyCustomError(42, "failed for some reason")'
    at Foo.test (contracts/Foo.sol:5)

Keep in mind that Hardhat can only recognize custom errors that are defined within your project. If you use mainnet forking and call some external contract that reverts with a custom error, Hardhat won't be able to parse it, and it will show an unrecognized error instead.
