fix(extension-code-block): #3604 paste code from vscode

[aliasliao]

fixes #3604 , #3321

This line (L267) causes the wrong insertion position:
https://github.com/ueberdosis/tiptap/blob/main/packages/extension-code-block/src/code-block.ts#L267

tr.setSelection(TextSelection.near(tr.doc.resolve(Math.max(0, tr.selection.from - 2))))

Removing L267 can fix the bug.
But I think the better solution is to replace selection with a text node, rather than imperatively inserting the copied content : )

@svenadlung need your review, please

@aliasliao Thank you. I'll have a look next week due to public holidays.

@aliasliao Sorry for the delay. There is a small difference in some cases. In that case the cursor after pasting is not in the code node, but in the following node. Can you please check again?

@svenadlung Hi, I have fixed (mostly) this issue in the latest commit. Could you please help to review it?

There is one last case that I found hard to handle: if there is a CodeBlock after the cursor before pasting, the cursor remains inside that CodeBlock after pasting instead of moving to the newly created code block.
