Add text/markdown as a supported mimetype for the Markdown UI.
Review Request #13654 — Created March 21, 2024 and submitted — Latest diff uploaded
More and more I'm seeing "text/markdown" as a MIME type for Markdown
files instead of the old "text/x-markdown". This change adds that as a
supported type for the review UI. This is a little bit moot because we
have some manual processing that assigns any.mdfile to
text/x-markdown, but we might as well be comprehensive.
Ran unit tests.
