Make typ the default code syntax

As far as I can tell this has been implemented:
With typ:

#lorem(1)

Without typ:

#lorem(1)

Now that this default has changed, I think it would be good to update How to post in the Questions category accordingly.

I propose this:

If your question pertains to a bit of Typst markup you have problems with, put it in the question body! You can syntax-highlight Typst code by wrapping it in ``` ... ```. For instance this typing this into your post:

```
#set font(size: 12pt)

Hello from *Typst* at $ pi.var + 1 $ o'clock!
```

Will be displayed like this:

#set font(size: 12pt)

Hello from *Typst* at $ pi.var + 1 $ o'clock!

If you need to highlight a code or math mode snippet instead, the language tags typc and typm do that, respectively. For instance: ```typc ...```.

To increase the likelihood of someone helping you find the solution to your problem, please post the smallest possible code samples that allow people to see what your problem is. If you paste this code into a new Typst document it should compile and demonstrate your problem.
