[vscode] Python formatter breaks comment pipe #| on code blocks

[eitsupi]

Currently, running a python formatter such as black on a qmd file destroys the comment pipe.

This code block

#| echo: true
print("foo")

To

# | echo: true
print("foo")

By auto formatting.

Perhaps the Quarto extension should protect the comment pipe as follows before letting the formatter run.

# #| echo: true
print("foo")

The same behaviour with jupyter ipynb and autopep8, using yapf as formater doesnt change #| comments

A quick hack to exempt #| from autoformatting when using autopep8 - disable E265 - Format block comments.

With the following config in Vscode :

    "python.formatting.autopep8Args": [
    "--ignore=E302,E265"
],

the #| is unchanged for me.

I used the recipe from here visual studio code - vscode python formatting autopep8 disable E266 - Stack Overflow
