Is your feature request related to a problem? Please describe.
Variables stored on friday will expire by monday since the retention period is set to 1.
https://github.com/UnlyEd/github-action-store-variable/blob/main/src/manageArtifacts.ts#L49

Describe the solution you'd like
If the value was set to 0 then it looks like the default retention setting would be taken.

Since GitHub Actions has released "saveState", this action is not as useful as before.

Therefore, I'm thinking of deprecating it, unless someone can tell me there is a utility to keeping it around (besides for the sake of not having to migrate existing code).

I'll keep the repo there regardless, even if I deprecate the action, but I'll probably Archive it if it isn't useful to anybody.
