feat(docs): adding the <doc:protractor> ngdoc-tag

This is the first step in migrating tests from <doc:scenario> to <doc:protractor>.
In-documentation examples with doc:protractor sections will have their contents
output to a tab on the docs site as well as output to a standalone test file in
build/docs/ptore2e.
