Replace ExpectedVersion::ANY() with proper version checks

[bwaidelich]

In the current core code we have 21 occurrences of ExpectedVersion::ANY().
Some of them are desired, for example in EventsToPublish::empty().

But all content-stream related events should always be published with the actual version of the respective CS (for example in SubtreeTagging::handleTagSubtree().

For workspace related events we should consider adding the workspace version to the read model, too, once those are integrated to the Content Graph projection (see #5038)
