Add "MIT License" at the top of acorn License file

Add a first line that specifies the license type "MIT License" this makes it more clear to developers which license is being used and can help them more easily determine if `acorn` is a package that they are okay to use in their software. [This is also the default for an MIT license for a repository when adding one in GitHub](https://github.com/joekrump/acorn/community/license/new?branch=master&template=mit).
