Frappe/ERPNext container image now built on debian bookworm

[revant_one]

• Debian 12 "bookworm" has been released! - Bits from Debian
• Use Python patch version 12 (3.10.12) instead of 5 (3.10.5). Old examples to build image with custom apps with incorrect version will fail. Official Python images for version 3.10 use bookworm only after versions 3.10.12. Using 3.10.5 will cause error as will not be able to pull bookworm image.
• Updated versions in docs frappe_docker/docs/custom-apps.md at main · frappe/frappe_docker · GitHub
• Check available tags here, Docker

If you need to build bullseye image override following build-arg:

• DEBIAN_BASE=bullseye
• WKHTMLTOPDF_VERSION=0.12.6-1
• WKHTMLTOPDF_DISTRO=buster
• PYTHON_VERSION=3.10.5
• NODE_VERSION=16.18.0

There is no reason to continue to build bullseye images, host OS can remain bullseye.
