[CONSTITUTIONAL] Register $BORING in the Arbitrum generic-custom gateway

After consideration, the @SEEDgov delegation decided to vote FOR on this proposal at the Snapshot Vote.

Rationale

As we previously stated in the case of Sky, a simpler and more streamlined process must be established to support builders seeking to migrate or bridge their tokens into the Arbitrum ecosystem.

The current frictions are evident. In this thread, @Jose_StableLab clearly pointed out that builders need more support and a simplified process. This would not only benefit builders, but also delegates, who currently must vote on every single token that seeks to be added to the official bridge.
