Fixes Issue

Description of Change

Update the "Example" and "Advanced Configuration" sections of the Gradle plugin documentation to use non-deprecated code samples.

Using a closure to configure proxy or data is now deprecated:

When adding this plugin to a project today, I noticed that a code snippet in my build.gradle, similar to examples in the documentation, was highlighted in IntelliJ as being deprecated. I'm not super well versed in Gradle, but I was able to quickly find a fix which works for configuring the DependencyCheckExtension and does not rely on using a closure.

I don't know what the best way to update the analyzers code sample in the configuration-aggregate documentation would be, though:

I feel like there's a better way to do it than the code below, so I did not include a change for this in my pull request. If anyone has suggestions on how to best write this configuration without using a closure, I'd love to hear your suggestions!

dependencyCheck {
    analyzers.assemblyEnabled=false
    analyzers.artifactory.enabled=true
    analyzers.artifactory.url='https://internal.artifactory.url'
    analyzers.retirejs.filters = ['(i)copyright Jeremy Long']
}

Have test cases been added to cover the new functionality?

no Because new functionality has not been added.
