Upgrade repo Dockerfile to Debian Bookworm

Same Debian Buster EOL fix as the API Dockerfile. Also adds
packages:write permission to the repo-push workflow.

Changes:
- debian:buster-slim -> debian:bookworm-slim
- Fix ENV syntax (legacy -> key=value format)
- libncurses5-dev/libncursesw5-dev -> libncurses-dev
- Remove python2 (not available in Bookworm)
- python3.7 -> python3.11
