Update dependency graph

Recent changes are not reflected in the dependecy graph here: https://docs.activitywatch.net/en/latest/architecture.html

Is there any abstract model to be described there? For example, for me it is a bit confusing to face two implementations of server and at least three implementations of client. And I'm talking only about reading the docs, not to mention presence of many more repositories on GitHub with names implying that there are even more implementations of everything.
