fix(cli): Split metadata.json per major version.

[FabianLars]

This is a hotfix to prevent the v2-alpha update prompt that all v1 users are seeing right now. releasing just a new cli patch version is not sufficient imo.

Also this is now missing the auto-update so it requires us to update it manually, but i'd prefer not to wait any longer until we can find a solution for this, unless someone else has an idea already because i don't have one i'm comfortable with rn.
