[JENKINS-73061] allow users with Overall/Manage to configure global plugin options

[mikecirioli]

https://issues.jenkins.io/browse/JENKINS-73061

Based on JEP-223, this operation does not allow users to escalate permissions and it's not related to security, so it qualifies to be accessible with the Overall/Manage permission.

Testing done

• Relevant URI related code was reviewed to ensure that file:// uri's were properly caught
• Installed plugin and manually verified a user with Overall/Manage can configure the feature. Also verified that no information was leaked when attempting to configure dodgy urls like file://etc/passwd, and secrets in JENKINS_HOME

@jetersen @rsandell @MarkEWaite Could i kindly get a review of this PR please?

[MarkEWaite]

@mikecirioli can you describe the interactive testing that you performed to confirm that it is behaving as expected? The "Testing done" section is the place where that should be described.

[MarkEWaite]

Looks good to me.

[mikecirioli]

@MarkEWaite I've updated the description to include the testing done, let me know if you need anything else
