Bump version to 0.0.29

WHAT:

The releases 0.0.25-0.0.28 broke the backward compatibility by removing the
"print this" selector "html2pdf" and replacing it with "html2pdf4doc" instead.

This brings in from upstream:
[feat(config): backward compatibility for legacy html2pdf selectors #182](mettta/html2pdf4doc#182)

WHY:

Preserve the backward compatibility for those users who might be using the
old StrictDoc versions (pinned) and sourcing the newer html2pdf4doc (non-pinned).

HOW: N/A
