Update documentation for running a cluster with MEV-Boost

[boulder225]

🎯 Problem to be solved

The documentation page for running a cluster with MEV-Boost on the Obol Network is outdated and does not reflect the current MEV-boost approach. There is confusion about whether to include details about the alpha feature in the documentation, especially since a related ticket was created earlier, but the page remains inaccurate.

🛠️ Proposed solution

• Evaluate Current Documentation: Review the existing page at Obol Network - Run a cluster with MEV-Boost to determine the specific inaccuracies and outdated information.
• Update MEV-Boost Approach: Implement the necessary changes to represent the current MEV-boost approach, aligning with the existing ticket #218.
