"Cannot open resource ..." error when using snap package

Issue Type: Bug

When opening a .wlnb file with the non-snap version of vscode, the file is correctly opened with the wolfram-language-notebook extension [1]. With the snap version, the following error is displayed:

"Cannot open resource with notebook editor type 'wolfram-language-notebook', please check if you have the right extension installed or enabled."

This happens with both on the stable and the insider channel. As this error only occurs with the snap version, I do no think it is an extension issue.
