Fence with `foo` in language

[paugier]

Context

I understood thanks to https://markdown-it.github.io/ that

```{admonition} This is my `admonition`
This is my note
```

is not parsed as a fence. However, it seems that it can be useful and "natural" for MyST users.

Proposal

I wonder if it could be possible to use ` in the info field of a fence?
