A lot of projects use Markdown formatting for their NEWS file now, since it’s human-readable, but also well defined as machine readable, and is rendered automatically when viewed online in GitHub or GitLab.

It would be useful if appstreamcli metainfo-to-news outputted valid Markdown, either by changing what the text format outputs, or adding a new markdown output format.

The main issue I’ve noticed with the existing text format is that the underline for the header is ~~~~~~ rather than the ====== or ------ stipulated by Markdown. I’m not sure if any other changes in the formatting would be required to make it valid Markdown.
