Properly handle exception from missing vscode config json file (#2728)

Today on main this exception is not caught and the Cursorless list
containing all the scopes is not filled which means that Cursorless is
not working if we can't find the vscode json config file.

## Checklist

- [/] I have added
[tests](https://www.cursorless.org/docs/contributing/test-case-recorder/)
- [/] I have updated the
[docs](https://github.com/cursorless-dev/cursorless/tree/main/docs) and
[cheatsheet](https://github.com/cursorless-dev/cursorless/tree/main/cursorless-talon/src/cheatsheet)
- [/] I have not broken the cheatsheet
