Remove security report summary from pipelines view

Problem

On the pipelines page, both security summaries are generated by different code. The code highlighted in 1. is actually barely translatable, because the sentence is actually split in two parts (the starting of the sentence and the link):

If we'd be able to re-use the same code which generates the summaries across both views, we can throw away a lot of duplicated code.

Original proposal

## Boring Solution

I would simply either make the whole sentence a link or add an Link Icon after it.

Proposed solution

Remove all security reports related information (indicated by red arrow in image below) from the pipeline info section and leave the Security tab as such.

TODO

After merge, we can close https://gitlab.com/gitlab-org/gitlab-ce/issues/48031 since it would not be applicable anymore.
