Thanks!

It's getting so complicated so quickly...

Well, we can also reduce complexity by accepting some odd versions like 0 or 0.0. (I'm fine with either.)

if [[ ! "${version}" =~ ^[0-9]+(\.[0-9]+(\.[0-9]+)?)?(-[0-9A-Za-z\.-]+)?(\+[0-9A-Za-z\.-]+)?$|^latest$ ]]; then

Maybe we should rewrite in python?

I'm not very familiar with python, so there is no possibility to do that in this repository.

Btw, as for reducing the complexity of install-action, improving maintainability, and support for #1, #5, #25, etc., I'm thinking of managing the package information as json or another and fetching the latest version's package information in CI to automatically update (like my other repos I mentioned in #5 (comment)).

I'm fine with this PR.

That will definitely makes updating a lot easier.
