tappx - Update adapter docs

[prebidtappx]

We have updated our dev-doc to correct data that was not correct.

actually, I'd like to discuss the colon in front of your brand. Can I get you to re-think that? Not fond of the sorting implications and the arms race it might spawn to get sorted to the top (or bottom) of the bidder list.

Hello @bretg
The colon is included in our name and whenever possible we add it (you can see it at https://www.tappx.com/, https: //iabeurope.eu/vendor-list / ...). When I reviewed this document, I realized that it wasn't included and so I corrected it.
If possible we would prefer to include it. I understand that the only impact would be a matter of order in the listings, right?

I checked out locally. Jekyll ignores the colon for sorting, so all good.

Thank you very much @bretg
