[enhancement] Add tag to next releases

[talensjr]

Hi! First, congrats for your work, I use it and it works really well. I faced an issue to which I made a pull request just to later on realise someone else already did it, which is great!, but it is merged on the versions/0.2.7 branch and I need to use it now, so I installed your package referencing that specific branch.
It would be cool if you can just add a "next" label (or tag) to that branch, so we can just install it as yarn add gatsby-plugin-intl@next
Thanks!
