Replace manpage build with multi-language mdbook docs in CI

- Remove manpage generation step and man2html dependency
- Add mdbook theme patching for language selector and utility links
- Repack tldr zip with pages/ prefix (uudoc expects this structure)
- Build translated docs via build-docs-l10n.sh for 18 languages
- Collect translated docs to /coreutils/docs-{lang}/
