honk e2e: put tube vk into vk tree

[ludamad]

VK verification got in and we're still trying to merge the initial honk e2e pass, we for now just make a special index for tube which always passes vk checks

I believe the tube vk is now being handled? @sirasistant

Nope, It's still a wildcard (unsafe) VK #9593 . Probably for testnet isn't a dealbreaker (since it's a sequencer circuit), but we'll need to be able to fix a set (ideally one or two) VKs for the tube for later releases. Currently BB is building an ad-hoc tube for every TX depending on TX complexity, which makes impossible to have it in the vk tree. CC @codygunton
