When the notes file already exists, the extension registers an error

[dlipovetsky]

When I "toggle" the notes open, and the notes file already exists, I see this in the "Window" output:

2022-12-12 17:26:44.688 [error] Error: Unable to create file '/home/user/project/.vscode/notes.md' that already exists when overwrite flag is not set

I'm not sure if there's a way to avoid this, given the API.

Thanks for the creating this extension! ❤️
