Use human readable names instead of ids in the vulnerability list for scanner type

Summary

If a user navigates to the security dashboard, in the vulnerability list we display the container type. The text displayed in the list is capitalised id values. We should use the names instead.

Steps to reproduce

1. Go to Security Dashboard
2. Check the vulnerability list

Here is a screenshot:

The column should contain texts similar to the filters. So for instance, instead of CONTAINER_SCANNING we should display Container Scanning.
