Use major version instead of exact version

[Apacelus]

Only set the major version to "force" "copy-paste" users to always use the latest version of the action by default.

This should avoid the need to delete older releases like what happened in #20

This works but only in the context of the current situation. But thanks, I'll merge this.

@thadguidry so this doesnt seem to work, neither with @v0.2, nor @v0 (or @v2).
Seems like you have to enable something as described here

WHAT specifically is not working for you. Can you give me some reproducible steps you are doing? or show me your workflow?

If you were trying to solve a problem of "force users to always use the latest version".
Then that problem is the problem I solved in the only way that is possible - break semantic version guarantees by removing older versions.
If you were trying to solve a problem of "warn users to always use the latest version".
Then that problem is not a problem to solve because notifications, as far as I understand, are not sent to workflow users of an Action, they might see a notice in their logs, but I don't think that happens and have not seen docs that explain if that happens or not. https://docs.github.com/en/actions/creating-actions/releasing-and-maintaining-actions

If you have found something that differs from my above understanding, then I'll be happy to review the docs.

My method of forcing users (breaking old workflows that have a semantic version guarantee - whereby I deleted prior version tags) is unpopular by many users in this circumstance, but it's the only way to truly force users to move forward.
