Make builds reproducible by default

Currently the plugin parameter `useDependencyVersions` is set to `false` leading to non-reproducible build (as the check is performed against a moving target). To have reproducible builds by default that parameter should be set to `true`. Also the readme should be clarified in https://github.com/adobe/aemanalyser-maven-plugin/blob/d2b7b530fb1ac8b0280c6c33560adedbcdb580f2/aemanalyser-maven-plugin/README.md#configuration that this also takes into account the SDK API version only listed in dependency management.

Find the plugin declaration for the useDependencyVersions parameter and inspect its current default. Update that default to true, then clarify the Configuration section in aemanalyser-maven-plugin/README.md to mention the SDK API version from dependency management; done means both the default and documentation reflect reproducible-build behavior.
