Test Case: Assess consistent versioning

[corbanvilla]

Setup the versioning testcase to pull directly from package.json.

Bonus Points

Write a script callable from package.json which uses sed to automatically update the version() return in all contracts.
Note: Some contracts use _version as the constant (ERC721Attributes) but most others use version as a public constant. Make sure to address both cases.

Subpackage package.json versions should be updated as well!

Extra Bonus Points

Extra bonus points if it's a Hardhat task where by default it only shows the changes it would make and allows the user to verify before running. Look for the -i flag under man sed.
