DOCS: add a LICENSE file to clarify open-source usage

[ThyToast]

Hi MYDS team,

Appreciate what you've done so far and it looks super helpful for a standardized look for government websites.

I noticed there's no LICENSE file in the repo. Since the README mentions it's open source, I just wanted to check if you're planning to add a license (like MIT, Apache 2.0, etc.) to make things official. It’d be great to know how the community can legally use or contribute to it.

Appreciate your time and the great work!

I've asked the same question before and I think it is related. #93
