docs: fix misleading OpenClaw install note and remove unsupported deploy command

[flobo3]

Fixes #322
Fixes #323

Summary

This PR addresses two documentation issues in the README.md:

1. Misleading OpenClaw installation note (README "fresh installation of OpenClaw" note implies a manual step that does not exist #322): The previous note stated that "NemoClaw currently requires a fresh installation of OpenClaw," which implied a manual prerequisite step. It has been reworded to clarify that NemoClaw handles the creation of a fresh OpenClaw instance inside the sandbox during the onboarding process.
2. Unsupported deploy command (Remove deploy command from Key Commands table in README #323): The nemoclaw deploy <instance> command was listed in the Key Commands table but is not part of the currently supported scope. It has been removed to avoid setting incorrect expectations.

Changes

• Reworded the Quick Start note regarding OpenClaw installation.
• Removed the nemoclaw deploy row from the Key Commands table.

Poem

🐰 I hopped through lines and made it clear,
No extra installs need appear,
Inside the sandbox a fresh claw grows,
One less command off the table goes,
Docs now whisper—welcome here! ✨
