Remove version/version_type options from Index::addDocument()

[pidera]

As mentioned in #2049, the version/version_type has been removed in 7.x as concurrency control.

These options were still always added in the addDocument method which causes an issue when adding a document from one index to another.

This PR removes those options, and sorts the other options alphabetically cfr #1803.

Thanks for the cleanup @pidera Any chance you could add an entry to the changelog?

Is my understanding correct that the test you added would not have passed without the change?

@ruflin I have added the changelog entry. And indeed, the added test did not pass without the change!
