For example, you might want to define a
next manifest id with upgraded dependencies versions, and from a specific branch of your MiniApps you can then run
ern upgrade-miniapp --manifestId next which will upgrade the MiniApp dependencies to the versions specified in the
next manifest entry, while your main MiniApp branches can continue tracking the
default Manifest entry. This was not possible previously due to the fact that Manifest entries had a one to one mapping to a specific platform version.
