* ops: Add bedrock-devnet script

Adds a bedrock-devnet script that deploys a local network using the Hardhat deploy scripts. I opted to write this in Python rather than Bash because we're starting to add complexity to our devnet setup, and I find Python much easier and safer to maintain.

Over time, I'll migrate the other devnet-up script to use this Python script as well.

To invoke this script, run `make devnet-up-deploy`. It's included in CI already as a separate testing job.
