RFE shorten name for the security scan

[Elyytscha]

Hello, i just noticed that this is a little bit escalating:

jenkins-plugin/stackrox-container-image-scanner/src/main/java/com/stackrox/jenkins/plugins/ViewStackroxResultsAction.java

Line 26 in 6380360

return "StackRox Report for " + getNames().collect(Collectors.joining(", "));

maybe something like

return "StackRox Report" 

would be better/enough

because as you see in the screenshot, with some images(had to blur it), this is really really huge:

It was added in #109 and at that time names weere ellipsed (...) as you can see on attached screenshots.

It looks like overflow: hidden was removed from this element causing entries to not be cropped. https://github.com/jenkinsci/jenkins/pull/6307/files#diff-a0dfd7912270518082206499b18f93a68b0c6fda759c616087612a64f5430284L114

How about changing it to number of scanned images if length is bigger than some number or remove repositories and SHAs?

[Elyytscha]

i'm happy with every of those solutions, but i think removing repos and SHAs could still be an issue if there are really lots of images built and analyzed in a repo

im also happy if this gets just ellipsed again
