add thirdweb plugin

[iankm]

Adding a new plugin for thirdweb's nebula API. We have one action that interacts with our natural language interface to read data from 2000+ blockchains.

Added, Readme, .env config and integration to default agent if key is set.

Here's an image with example usage (through my agent, Breakout Bro):

if you merge this one, we should be good to go. It should resolve the conflicts, but would need one last quick test as this repo is moving fast
