Doesn't work in Astro 3 anymore

[shishkin]

This integration doesn't with in Astro 3 anymore. Astro refuses to render the generated/transformed AsciiDoc JSX page:

 error   Unable to render `Content`.

  No valid renderer was found for this file extension.

I was unable to troubleshoot the issue and raised it with Astro team a few times (without any response so far):
