Create a Markdown formatter for Documents, Slides, Office type of Media

[DiegoPino]

why?

Well, thinking loud about options to transform/transmute for inline rendering DOC/DOCX/PPT/ETC having something that can display/render the content of an .MD file is crucial.

Seems like 'drupal/markdown:2.x-dev' module is good for this. I don't want to write a module from scratch, i just want the rendering capabilities. Since that module provides Twig templating options and also at the same time a fully blown renderer as a service, i feel we can use both.

So what is needed?

1.- On Archipelago-deployment beta3 include the new dependency in composer? not really needed but just in case and enable the module in the sync YAML folder , and also a command line / script for updating beta2 dependencies and auto enabling via drush (that is like another issue itself)
2.- On this module beta3 add the dependency to composer.json and create the new formatter. the formatter should be able to read .MD file content. Just with the fact it will be enabled inside metadata displays enabling it should be no-code/straightforward
