Help needed: Is it possible to enable "vanilla" prism.js syntax, i.e. with the `language-` prefix?

Nobody has claimed this yet.

Hello,

My workflow involves editing the same markdown files with multiple apps. After incorporating MacDown into this workflow, I noticed that prism.js behaves differently in MacDown and other apps. In order to get syntax highlighting work properly in each app, I have to do the following:

In MacDown,

```
```c
\\Some code written in C
```
```
In other apps,

```
```language-c
\\Some code written in C
```
```
As a result, the same markdown files cannot be highlighted properly *at the same time* in MacDown and other apps because of the incompatible implementations. After consulting the dev team of other apps, I was informed that the second way is the "official" prism.js syntax and that I should contact MacDown dev(s) instead.

So, is there already some way that allows me to enable the "vanilla" prism.js syntax? If not, could you please consider adding this option?

Start by tracing MacDown's Prism.js syntax-highlighting integration and how Markdown code fences are converted. Check whether the integration accepts the language- prefix alongside the existing form; done means code fences using that prefix receive the expected syntax highlighting without breaking current behavior.
