This commit shades the use of 'com.vaadin.external.google:android-json'
in the three modules that use it. The configuration processor already
did that and this commit does the same for configuration-metadata and
the CLI.
As a result of this commit, 'android-json' is not used nor managed
internally.
Closes gh-45504
