The extension doesn't open for any of the suggested file extensions

[TomasHubelbauer]

Hi, just installed the latest version of the Excelidraw extension and tried to use it by creating a test.excelidraw, .excelidraw.json and test.excelidraw.png files and opening them, both done from the VS Code Explorer pane. In the .excelidraw and .excelidraw.json cases, the files just opened as usual, as if there was no Excelidraw extension installed at all. In the .excelidraw.png case, I first got a hint that the PNG file was broken and could not be previewed and then VS Code asked me to fall back onto the default text editor, so very similar.
