feat: Add-blockscout_params

[zt-9]

fix #837
the default blockscout image version does not work on my machine.
so i added the blockscout_params for blockscout service. now user can customize the image versions they want to use.
it contains two params:

blockscout_params:
  # blockscout docker image to use
  # Defaults to the latest image
  image: "blockscout/blockscout:latest"
  # blockscout smart contract verifier image to use
  # Defaults to ghcr.io/blockscout/smart-contract-verifier:v1.9.0
  verif_image: "ghcr.io/blockscout/smart-contract-verifier:v1.9.0"

i already tested it on my machine and it worke well.

The newest version of blockscout also has a frontend image.
Also currently their latest image is incompatible with kurtosis.
