Bug 35417: Update breadcrumbs and page titles for vendor issues

This patch updates the vendor issues template so that title and
breadcrumbs follow the same pattern on other updated templates:
Translatable strings in the title and breadcrumbs using the template
WRAPPER.

To test, apply the patch and go to Acquisitions.

- Search for a vendor and view the details.
- Click the "Isssues" link in the sidebar.
- Check that the page title and breadcrumbs are correct in each
  variation of the page:
  - The main page
  - New vendor issue
  - Modify vendor issue
  - Issue deletion confirmation
