Run `yarn add --dev hardhat@2.9.3`

## Importing from NPM
There are changes in the @chainlink/contracts dependency, if you install the latest version you will end up in an error:
'Error HH404: File @chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol, imported fr/FundMe.sol, not found.'

To avoid this specify the version used in the course:
`yarn add --dev @chainlink/contracts@^0.3.1`
