Add v1 meta tag

[milliams]

According to the docs, as well as following SemVer, actions should:

Move the major version tag (v1, v2, etc.) to point to the Git ref of the current release

This is so that users can just do:

uses: actions/upload-release-asset@v1

and always be on the latest, compatible release.

There is an action which claims to be able to do this automatically for you at https://github.com/marketplace/actions/actions-tagger

Refs actions/create-release#16 and actions/toolkit#214

Indeed, it would be nice to add a v1 tag to this action, per the official versioning documentation: https://github.com/actions/toolkit/blob/master/docs/action-versioning.md

Right now, everyone is hardcoding @v1.0.1 which means it's going to be painful if something breaks as nobody would get the bug fix automatically.

Could one of you add a v1 tag to this action?

I just setup that action to automate it in #27. Thanks for your patience around this!
