Create a new ready_to_merge.vue component to match designs
As part of the restructuring the merge request widget we will need to create a new ready_to_merge.vue
component to match the designs below.
The reason we need to create a new component here is that we will be refactoring the ready_to_merge.vue
state component here to be re-usable across the whole widget.
This component should actually be relatively straight forward in that it is mainly just copy with a slight change in copy when the user does not have the right permissions.
