chore: migrate RL scanner to shared devsecops-tooling action (#837)

Migrates the RL scanner from the repo-local workflow + composite action
to the shared `auth0/devsecops-tooling/.github/actions/rl-scan@main`
action.

**Changes:**
- Replace the old `rl-scanner.yml` reusable workflow and
`.github/actions/rl-scanner` composite action with a single inline job
using the shared action
- Wire `publish-pypi` to depend on `rl-scanner` via `needs:`
