Mark Plugins Data and Events as stable (#346)

* Mark Plugins Data and Events as stable

Remove the @Unstable annotations form the data and BesuEvents services.
This means that no breaking changes (like removing methods or
changing signatures) will occur without proper notice and versioning
bumps.

* tweak build check
