Non-admin user use 'Allow Download' option for Xray blocked artifacts

Problem statement:
Xray blocks a vulnerable artifact in artifactory and an artifactory user who has non-admin permissions can also override this blocking by clicking on artifact -> Xray Tab -> Allow Download option.

Impact:
A user who is not supposed to allow downloads of a blocked artifact can do it.

Steps to reproduce:

• Deploy a vulnerable artifact to a local repository
• Scan it using Xray and create a policy to block artifact
• See that the artifact is blocked in artifactory
• Create a user with upto delete/overwrite permissions to local repositories in artifactory
• Login with this user and notice that you can choose 'Allow Downloads' for the blocked artifact
