chore(xrpl): remove token instance registration script & update guides

[k4m4]

As of XRPLGateway v1.3.2, token instance registration doesn't need to be performed manually: commonprefix/axelar-amplifier#29.

Hence, we remove the outdated register-token-instance script and update the XRPL token deployment guides.

---

Note

Removes manual token instance registration by deleting the script and updating XRPL deployment/linking docs to drop that step and renumber.

• Code:
  • Delete deprecated xrpl/register-token-instance.js.
• Docs:
  • xrpl/README.md: Remove Register Token Instance section.
  • xrpl/docs/deploy-local-token.md: Remove step for token instance registration; update instruction to repeat steps 4-7.
  • xrpl/docs/deploy-remote-token.md: Remove XRPL Token Instance Registration section.
  • xrpl/docs/link-token.md: Drop token instance registration step; renumber subsequent steps (remote token registration and mint role grant).

Summary

This PR removes outdated manual token instance registration functionality from XRPL token deployment workflows. The changes are driven by XRPLGateway v1.3.2, which now automatically handles token instance registration that previously required manual intervention via a dedicated script.

The PR eliminates the register-token-instance.js script entirely and updates all related documentation across three deployment guides: link-token, deploy-remote-token, and deploy-local-token. The documentation updates involve removing step-by-step instructions for manual token instance registration and renumbering subsequent steps to maintain proper flow.

This change simplifies the token deployment process by removing a manual step that was error-prone and is now handled automatically by the gateway contract. The updates ensure that users won't attempt to perform deprecated manual registration processes when the system handles this automatically.
