How to ensure the build is using the same git hash

[drekka]

So I have a flow where the first job gets the version data using your action, then the second job does a series of builds based on a matrix. Now if I want the version to locate the latest tag, I assume I'm going to need to pass something to the build job so it can also checkout that same tag.

I figure I can do it by re-contructing the tag from the passed version data and telling checkout to retrieve that tag. But I'm wondering if there is a better way, or perhaps whether semver could also publish the hash of the tag.

Thoughts?
