Monorepo flow: Warn the user if any packages in the release spec fall outside the set of changed packages #10
Description
When editing the release spec, the user technically has the opportunity to modify the set of packages listed there, but this should be discouraged as much as possible, because it means that it is possible to release a package that relies upon another package which is not being published. For instance, say B is bumped and A is bumped but only B is released. This may work just fine in development and on CI but will not work in production. We want to prevent this from happening.
