Removal of SecureRPC (Manifold) from Lido's relay list due to sustained unavailability

Thanks for the proposal. I have shared it with the others in the RMC. I’ve also seen the downtime by Manifold. Reaching out to them so far has not resulted in a response so I’ve suggested to go ahead with the removal. As a reminder - as of last year these changes are made through easytrack motion. I will share the vote once it’s made on-chain.
