Add LICENSE file to repository + confirm with website contributors

[davelester]

The package.community website repo is currently missing a LICENSE file, and I'd like change that by adding the MIT License.

@zkat @legodude17 Can you comment + give your permission to include your past contributions to the repository under the new license?

@legodude it looks like you have one outstanding PR that I'd like to apply this to as well.

Thanks! After confirming I can send a PR over for the change along with additional website improvements.

MIT is fine by me :)

MIT sounds good!
