README.md generated HTML is being rendered in quoted string on homepage for some reason

I updated to oranda 0.6.5 to add to an existing Oranda site: https://hickory-dns.org. The README.md is part of a git submodule. The site config is pretty basic:

```
{
"styles": {
"theme": "hacker",
"favicon": "static/favicon.ico",
"logo": "static/logo.png"
},
"project": {
"name": "Hickory DNS",
"readme_path": "hickory-dns/README.md",
"repository": "https://github.com/hickory-dns/hickory-dns",
"license": "MIT OR Apache-2.0"
}
}
```

https://github.com/hickory-dns/hickory-dns.github.io/blob/main/oranda.json

After the update, this got produced in the body, when served locally, you can that the body of the README.md is escaped on inclusion in the primary home page document:

```
...

<p><a href="https://www.whatrustisit.com" rel="noopener noreferrer"><img src="https://img.shields.io/badge/minimum%20rustc-1.70-green?logo=rust" alt="minimum rustc: 1.70"></a>
...
```

Is there something that I need to change?

Reproduce the issue with the linked oranda.json configuration and the README.md supplied through the git submodule. Inspect the generated homepage HTML and compare the README content before and after generation. Done means the README renders as HTML on the homepage rather than as escaped text.
