chore: fix versioning of bn254_blackbox_solver crate (#4638)

# Description

## Problem\*

Resolves #4634 

## Summary\*

The ACVM crate publishing steps are failing because when
`barretenberg_blackbox_solver` was renamed to `bn254_blackbox_solver`
the release please config wasn't updated to match, resulting in the
version not being incremented on releases.
