chore: Change blob ID calculation in forc-deploy to use configurables offset (#6991)

## Description

Closes #6990

The main change here is switching from using the data section offset to
using the configurables offset in the blob loader in forc-deploy.

TODO: update the loader-abi.json test file(s) once deployment to testnet
is working.
