Support `console` language on code fences

For highlight interactive console sessions, the console code fence would be a nice thing to support.

[github language config](https://github.com/github-linguist/linguist/blob/master/lib/linguist/languages.yml#L6703)

example:

````
```console
oranda dev
↪ >o_o< INFO: Found 1 paths to watch, starting watch...
↪ >o_o< INFO: Building components: artifacts, changelog
⚠ >o_o< WARNING: Found syntax highlight language annotation `console` which is not currently supported. The annotated block will be shown as plaintext. Please file an issue https://github.com/axodotdev/oranda/issues/new to let us know you'd like to see it supported.
```
````

rendered:

```console
oranda dev
↪ >o_o< INFO: Found 1 paths to watch, starting watch...
↪ >o_o< INFO: Building components: artifacts, changelog
⚠ >o_o< WARNING: Found syntax highlight language annotation `console` which is not currently supported. The annotated block will be shown as plaintext. Please file an issue https://github.com/axodotdev/oranda/issues/new to let us know you'd like to see it supported.
```

Please let me know if there is a different language to use for these kinds of code blocks
