Deleted Notebooks remain open in the editor

Environment data

• VS Code version: 1.52.1
• Extension version (available under the Extensions sidebar): v2021.1.502429796
• OS and version: Ubuntu 20.04

Expected behaviour

Consistency when deleting files. When you delete any file in the explorer, the file is removed from the editor window.

Actual behaviour

If you delete an ipynb file in the explorer, the notebook remains open. This makes it really easy to accidentally edit the deleted file (or even run a cell) which results in it being recreated.

Steps to reproduce:

1. Open a notebook
2. Delete the file in explorer

This also occurs with rename, if I rename an open ipynb it doesn't close / reopen the original notebook.

Thanks for the bug.

This should be addressed when we switch over to VS code's new notebook API. Please track this issue for when we switch:
#1231.

You can try it yourself if you use VS code insiders.

Thanks for your feedback. This issue will be addressed once VS Code adds native support for editing notebooks. Please see microsoft/vscode#91987.
