Replace fragile debugpy installation with Red Hat package repository

[coderabbitai]

Context

In jupyter/trustyai/ubi9-python-3.12/Dockerfile.konflux.cpu around line 254, the debugpy installation uses fragile TOML parsing and bypasses hash verification:

• Uses grep -A1 '"debugpy"' ./pylock.toml | grep -Eo '\b[0-9\.]+\b' to extract version (brittle to TOML formatting changes)
• Installs via git+https://... which bypasses hash verification, inconsistent with --verify-hashes used elsewhere

Proposed Solution

Replace with Red Hat package repository installation:

• Use https://packages.redhat.com/api/pypi/public-rhai/rhoai/3.4-EA1/cpu-ubi9/simple/debugpy/ for CPU builds
• Use https://packages.redhat.com/api/pypi/public-rhai/rhoai/3.4-EA1/cuda12.9-ubi9/simple/debugpy/ for CUDA builds

This will:

• Maintain hash verification
• Remove brittle grep parsing
• Stay consistent with --verify-hashes posture
