LGTM. Does this change affect tutorials or other docs?

I checked all docs in this repo. I don't think there is any other.

I ignored that in CHANGELOG.md.

@rennyG Do we need to update other files?

@rennyG Do we need to update other files?

I did a search on this key/value in the shopify-dev repo, and it looks like no manual changes required there. When this PR is merged, though, we'll want the changes ported to shopify-dev. Let me know if you need a hand with that.
