Unable to render \${...} in code block

Subject of the issue

Feel free to close if this is not a bug (or bug of some other library).

I’m trying to render the following

```
python command subdir=\${model.nb_layers}
```

but it crashes because MDX tries to evaluate the contents of the ${...}. I suspect some double escaping occurs and the problem (if indeed a problem) lies in this line. Or it could be a remark issue. Not entirely sure which.

I also posted on Spectrum here because I wasn’t sure whether this was a bug.

Your environment

• OS: macOS 10.15.1
• Packages: @mdx-js/mdx@1.15.1
• Env: Node 8.16.2, Yarn 1.16.0

Steps to reproduce

Repo here - https://github.com/yangshun/hydra/blame/master/website/docs/configure_hydra/workdir.md#L67-L69

Expected behaviour

Renders fine. It renders ok for GFM.

Actual behaviour

MDX tries to evaluate the contents of the ${...}. I suspect some double escaping occurs.
