Remove trailing and leading single/double quotes from path

[disberd]

Fixes #1639

Should not break existing valid names containing quotes as it only remove the trailing and leading character if there is a quote after the notebook extension

A bit niche, but sure..

But can you make it very strictly only work when both the first and last character are double quotes?
And also add a comment referring to the issue you made.

Done, I also kept single quote as option as I suppose there are cases where the path are pasted surround by them but I can remove them if you think they are breaking something.

[dralletje]

It's not about breaking stuff, but about keeping the code we insert for an exception really simple and easy to follow (e.g. path_or_url[0] === '"' && last_char === '"' vs whatever there is now). I know the difference seems silly, but having an special handling like this really needn't be something we do often :P

Also can you use .slice instead of .substring? That way you can write .slice(1, -1) 😎

Also also, can you run prettier? Now if I open the file I get a diff instantly because of the formatting

[disberd]

Makes sense, I have the tendency of try to take into account too many un-necessary corner cases...

Thanks for the slice suggestion, my Javascript expertise always relies on google what I want to achieve :D.

I removed the definition of last_char since probably is clear enough with indexing the string directly.
Let me know if that is OK.

I didn't have any prettier as I started this edit directly on the web github interface but this time I pulled this branch on VSCode to prettify.

Thanks a lot! Sorry for making you go through 2 edits :P
