DistributionManagement site field uses incorrect type

[Eric Ortega]

effective-pom files containing a "site" section are failing when parsed via the CLI.

      <site>
        <id>apache.website</id>
        <url>scm:svn:https://svn.apache.org/repos/asf/maven/website/components/ref/3-LATEST</url>
      </site>

Attempting to analyze the file leads to the following error.
