Edit language for codeblock highlighting

[vemonet]

Currently Marker does not seems to support editing language for codeblock highlights e.g.

```python
import os
```

Would be nice to have this!

The app supports syntax highlighting for code blocks (with language identifiers). Could you clarify more on what you're talking about?

In the editor, I cannot change the language of an existing codeblock, I cannot even see which language is defined for this codeblock

But, indeed creating a new codeblock with a specific language works well

Ideally I would expect that when clicking inside a codeblock there would be a little popup at the bottom right or top right of the codeblock with a text field that shows the language (and autocomplete based on all available languages ideally!). A bit like you have done for Links

Note I am using Ubuntu 22.04 with xorg display (in case that might be a bug)

Really cool implementation btw! Clean code and user-friendly interface, there are not a lot of good markdown editor out there. And this new one might be the best one! Typora is really good but closed source, and Marktext/Muya is ok, but the underlying JS code seems quite messy. Using tiptap for the editor looks really good and fitting the need

Thanks for the feedback, added this in v1.0.1.
