Fixes Franka blueprint env ID in docs (#3213)

# Description

Replace the incorrect env ID `Isaac-Stack-Cube-Franka-Blueprint-v0` with
the correct `Isaac-Stack-Cube-Franka-IK-Rel-Blueprint-v0` on the
environments list page to match what’s registered in code and shown by
`scripts/environments/list_envs.py`.
