Extend TipPluginInterface with ConfigurablePluginInterface

This extension is being deprecated, see 🌱 [Meta] Tasks to deprecate Tour module Active . It will be removed from core and moved to a contrib project, 📌 [11.x] [Meta] Tasks to remove Tour Postponed .

This is now Postponed. The status is set according to two policies. The Remove a core extension and move it to a contributed project → and the Extensions approved for removal → policies.

Moving over but blocking ticket #21 is still not complete after 7 years wonder if we can do something else in contrib.

Since we are moving Tour UI over in contrib version 2.0.x think it would be good to get something in for this. The trait ticket is all but stalled (happens). So think we can go forward with another.
