[Instrumentations] ActivitySource and Meter versioning

[Kielek]

LGTM: There is still open question on how to handle the version when instrumentations do not create the ActivitySource for the activities they enrich. None of the libraries here falls under that category.

@Kielek - We could open issues for the special cases in their respective repos.
