Display list of "Other amendments on parent license" on Amendment view

Purpose:

User story statement(s):

As an ERM librarian
I want to be able to see a list of other amendments on the parent license from the amendment I am currently viewing
so that I can more easily differentiate between amendments

As an ERM librarian
I want to be able to navigate to other amendments on the parent license from the amendment I am currently viewing
so that I can more easily move between amendments on the same parent license

Scenarios:

1. Scenario:
   • Given a parent license with more than one amendment
   • When I view one amendment
   • Then
     • I see an accordion headed "Amendments on parent license"
     • I see a badge in the accordion showing the number of amendments on the parent license
     • on opening the accordion I see an MCL list of all amendments on the parent license with their Name, Status, Start date and End date
2. Scenario:
   • Given a parent license with only one amendment
   • When I view that amendment
   • Then the "Amendments on parent license" accordion does not display

The MCL displaying the list of amendments is the same as that used to display the list of amendments on the License view
