Fix broken LayerZero links; migrate Goerli → Sepolia in bridge guide

Changed in

• learn/onchain-app-development/cross-chain/bridge-tokens-with-layerzero.mdx
• Public page: https://docs.base.org/learn/onchain-app-development/cross-chain/bridge-tokens-with-layerzero

What changed? and why?

• **Changed in https://docs.base.org/learn/onchain-app-development/cross-chain/bridge-tokens-with-layerzero
• Fixed broken LayerZero links to match current LayerZero V2 documentation.
• Replaced Goerli with Sepolia (Base/Optimism) since Goerli is deprecated and LayerZero examples target Sepolia.
• Aligned examples so the OApp flow works on Sepolia.

• Scope is limited to this single page.
• All links now resolve to the intended LayerZero sections/resources.
