// This script calls deposit() on a ObolValidatorManager contract.
// To run this script, the following environment variables must be set:
// - PRIVATE_KEY: the private key of the account that will deploy the contract
// Example usage:
// forge script script/DepositScript.s.sol --sig "run(address)" \
// --rpc-url https://rpc.pectra-devnet-5.ethpandaops.io/ --broadcast "<ovm_address>"
// forge script script/DepositScript.s.sol --sig "run(address,string)" -vvv \
// --rpc-url https://rpc.pectra-devnet-5.ethpandaops.io/ --broadcast "<ovm_address>" "<deposit_file_path>"
