Add opBNB mainnet data on Dune

hello Dune team, a lot of people have their eyes on opBNB right now. I personally am working with a few teams that are launching their own projects on opBNB. It would be super helpful to have opBNB data on Dune ready for analyses. thanks a lot for all the great work you've done! look forward to digging into opbnb data on Dune real soon!
