Added workflow for mangrove mapping

@eriklindquist , I'm not sure why RTD is not automatically creating the preview, but FYI, this is automatic build created after your commit https://sepal-doc--584.org.readthedocs.build/en/584/workflows/mangrove_mapping.html

Hi @eriklindquist — the RTD build failure is not related to your changes. The sphinxcontrib-youtube package recently bumped its minimum Sphinx requirement to >=7.2, which conflicts with the Sphinx<=7.1.2 pin we had in requirements.txt. We've already fixed this on main (#585), but since your branch was created before that fix, RTD picks up the old pin.

Everything else looks good — we'll go ahead and merge. The conflict will resolve automatically once your changes land on main.
