"Show Markdown File" - Linux compatibility

[hektor]

Would it be possible implement "Show Markdown File" on Linux? At this time it just opens the parent directory (which is kind of useless as you would still have to look up the file).

showSelectedItemMarkdownInFilesystem: function (idx) {

        const entry_res = this._getSelectedEntry(idx);

        const file = new FileUtils.File(OS.Path.normalize(entry_res.path));
        if (file.exists()) {
            try {
                Zotero.debug("MarkDBconnect: Revealing " + file.path);
                file.reveal();
            } catch (e) {
                // On platforms that don't support nsIFile.reveal() (e.g. Linux),
                // launch the parent directory
                Zotero.launchFile(file.parent);
            }
        }
    },

I was thinking of running xdg-open with file.path as argument, but am not sure if/how this would be possible.

My choice of implementation for linux was based on Zotero's, e.g.

https://github.com/zotero/zotero/blob/2f0d41c0cb9ea47cce03ea51bf8ac718dbe44b15/chrome/content/zotero/zoteroPane.js#L4922

I don't have easy access to a linux platform so it's not easy for me to test other solutions. And given that this is the best solution that Zotero came up with, it's not a feature I'm going to prioritize.

That said, if you (or anyone) find something that works I'd be happy to add it.
