GitHub-Flavored Markdown only permits certain allow-listed tags and attributes in inline HTML:

You can use a subset of HTML within your READMEs, issues, and pull requests.
A full list of our supported tags and attributes can be found in the README for github/markup.

and itemtype
attributes are allow-listed, in addition to the general attribute allowlist:

An alternative would be to put together a GitHub Pages site, which seems to be much more flexible.
