Add all available package identifiers to extended package information in the package view

Purpose:

We now populate additional identifiers for packages, but do not display all of them in the main display due to space and priority. However it would be useful for the user to be able to see where there are additional identifiers, so this story is to add them to a table under the "Extended package information" accordion

User story statement(s):

As an ERM librarian
I want to see all the identifiers available for a package
so that I can use alternative identifiers as appropriate (e.g. when talking to a provider about their package use a provider specific identifier)

Scenarios:

1. Scenario:
   • Given the Extended package information in the package view
   • When there are identifiers for the package
   • Then I see an MCL displaying a list of the identifiers with two columns:
     • Type (populated with the identifier.namespace.value)
     • Identifier (populated with the identifier.value)
   • The MCL should display as the last thing in the accordion (below the alternateResourceNames)

Additional information
