Provide Clarity regarding base deployment addresses

[ckoopmann]

The Base chain is not mentioned in the deployments.md.
It doesn't seem as if they are deployed under the addresses listed there.

This should be fixed as it is highly confusing and should be cleared up. It seems that already some people have tried to swap on base using the old SwapRouter address and lost funds as a result.
