Subject: [PATCH 05/11] A few fixes in rcrcrc action (#2338)

**Context:**
We fix a few things regarding the rcrcrc script, and xdsl dependency.

1. Adds explicit `rc0` lower bound to rcrcrc pip install
2. Adds apt install graphviz to rcrcrc
3. Remove xdsl from `requirements.txt`, since it is already in
`setup.py`.
