Production bundler config setup for EPv0.7

[veljkovranic]

What?

Create and setup new bundler config in production GCP cluster.

Why?

After the introduction of EntryPoint v0.7, several new fields are added to the configuration file. Those must be present in order for the new bundler version to run.

How?

Take a value of GCP variable, add new fields populated for Base Sepolia and Mainnet and save the new version in the same GCP variable.
