py does not trigger nested Python tree-sitter to work, but python does

[Andrew15-5]

This doesn't add Python syntax highlighting:

```py
print()
```

But this does:

```python
print()
```

While both work fine with Markdown tree-sitter.

Checked on Neovim and Helix.

With Helix, this fixed the problem: helix-editor/helix#10785. But I have no idea what to do in Neovim/tree-sitter if anything can be done.

Instead of https://github.com/uben0/tree-sitter-typst/blob/master/queries/typst/injections.scm#L4-L6,
try the following:

(raw_blck
  lang: (ident) @_lang
  (blob) @injection.content
  (#set-lang-from-info-string! @_lang))

It turns out that for Neovim, this exact code is a part of https://github.com/nvim-treesitter/nvim-treesitter. So I did:

diff --git a/queries/typst/injections.scm b/queries/typst/injections.scm
index 344c6a30..bc75d2b2 100644
--- a/queries/typst/injections.scm

   (#set! injection.language "comment"))
 
 (raw_blck
-  (ident) @injection.language
-  (blob) @injection.content)
+  lang: (ident) @_lang
+  (blob) @injection.content
+  (#set-lang-from-info-string! @_lang))

And now it works! I will have to make 2 PRs, I guess.
