[JENKINS-39737] Update UI to support new artifacts endpoint - Jenkins Jira

In Scope

Update the loading of the artifacts tab so that it fetches its data from the new artifacts endpoint built in ~~JENKINS-39761~~ (similar to how we load the test tab)
Ensure that the name of the artifact is the "full path"
Add a download all button to the Artifacts tab (see screenshot of https://ci.jenkins.io/job/Plugins/job/pipeline-model-definition-plugin/job/master/lastSuccessfulBuild/artifact/)
If we are showing the maximum number of artifacts then show message below "Showing first 100 artifacts"
