Add Lodestar voluntary-exit command to the Obol Launchpad UI.

🎯 Problem to be solved

For Obol users who are using the Lodestar VC, the information should be relatively available to demonstrate how to voluntary exit validators on the Launchpad UI. It currently does not exist on the Launchpad for any of the networks as seen on the screenshot below:

The solution is within another page inside of: https://docs.obol.tech/docs/start/quickstart-exit

• Link to the codebase issue that prompted this docs change

🛠️ Proposed solution

Lodestar should be added in the Launchpad UI to demonstrate how to exit validators:

Holesky:

docker exec -it charon-distributed-validator-node-lodestar-1 /usr/app/lodestar validator voluntary-exit --beaconNodes="http://charon:3600" --dataDir=/opt/data --exitEpoch=${EXIT_EPOCH:-112260} --network=holesky --yes

Mainnet:

docker exec -it charon-distributed-validator-node-lodestar-1 /usr/app/lodestar validator voluntary-exit --beaconNodes="http://charon:3600" --dataDir=/opt/data --exitEpoch=${EXIT_EPOCH:-112260} --network=mainnet --yes

• For major overhaul of docs, design doc link:

🧪 Tests

• Netlify deployment build tests passing

👐 Additional acceptance criteria

❌ Out of Scope

Start with the Launchpad UI documentation page and the existing quickstart-exit page at docs.obol.tech/docs/start/quickstart-exit. Add the Lodestar voluntary-exit commands for Holesky and Mainnet, then verify that the Netlify deployment build passes and both networks display the instructions.
