Fix security scanning tools so that reports make sense

[jimmykarily]

Because currently they report errors but we don't know what's wrong: https://github.com/kairos-io/kairos/security/code-scanning

Also, let's update the GH release ticket template so that it links to the places where we should check for CVEs before we release (e.g. framework security tab, kairos security tab etc)

We added a -trivy and -grype suffix (e.g. here) but the old "configurations" where still dangling (they are created on the fly when we push some results with a category string). I deleted the old configurations and it cleaned up the tool warnings.

The results still fail to load most of the time but with enough refreshes I can get them to show up if I filter by tool (so there are less to load I guess).

The reports still don't load in the web ui. @Itxaka opened a ticket on GH support.
