The VSCode extension uses a project abstraction to build up key metadata about
the structure of Solidity files in the workspace and how to compile them.

Currently the extension supports the following project types:

• Hardhat v2
• Foundry
• Truffle
• Ape
• None - the no development framework project type

We will need to add a new Hardhat v3 project type that will:

• identify Hardhat v3 projects
• read the Hardhat config to retrieve key information e.g. the default solidity version
• identify solidity files that should be included in the project
