While trying to update the homebrew formulae, I found the license text is little bit wild, and I used Unlicense to better reflect the intentions of the license, but obviously, it is still not an OSI-approved license, which might cause some confusion down the path.

I think we can pick and choose from the following license moving forward so that we can make sure it is loud and clear :) :

• https://spdx.org/licenses/CC0-1.0.html
• https://spdx.org/licenses/Unlicense.html

relates to https://github.com/Homebrew/homebrew-core/issues/58225#issuecomment-667761517

I see that "Unlicense" was already stated as the license without this project's approval. Please do not think to speak for rbenv-gemset.
