fix(jito_rpc): makes jito bundle atomic

[0xzrf]

Summery

Simulates each transaction sent in the sendBundle rpc method and early returns if any of them fail.

Changes

• Adds an iterator inside the SurfpoolJitoRpc::send_bundle function before sending transactions
• Adds test to check if it returns the right error message

Note

This might not entirely replicate jito bundles. But since it's majorly used for testing purposes, it works well to say that the bundle is atomic

Closes #594
