Fix Docs: remove the op-nodes/CLs coupled with rbuilders in the network diagram of the rollup-boost HA setup

[yashvardhan-kukreja]

Currently, in the hackerdraw diagram of rollup HA here, every rbuilder is coupled with a CL (op-node).

But there's no mention of its significance in the content of that documentation.

Moreover, over a conversation with Flashbots team, it was confirmed that the op-node (CL) on the sequencer's side is significantly enough to lead the FCU without the need of an op-node coupled with rbuilder.

PS: Even in the following sequence diagrams, only the sequencer's op-node/CL is shown to guide the FCU all on its own.

Therefore, the flow chart shouldn't have op-nodes coupled with rbuilders.
