Add a no-single-quotes rule to enforce a fancy closing single quote

[matthemsteger]

This adds a rule that we find useful in our static gettext translation. From a design perspective, we want to only use the fancy single quote (closing single quote) and disallow the regular single quote that engineers usually use everywhere. It is more typographically sound. https://practicaltypography.com/straight-and-curly-quotes.html

This library is wonderful and is a great place to put this gettext style enforcement. I mostly copied the existing implementation.

• It enforces the same parameter stuff as the other rules
• It accepts (does not fire a violation) when parameters are not string literals, it only applies to string literals

I think this would be awesome if we'd also make it auto-fixable. This would be much better than simply showing an error

[matthemsteger]

I can take a stab at that

BTW, the CI was failing because we were still referencing nsp in the repository. I've removed it from master, so if you rebase the CI will run on your PR.

Hey your PR is good, could you check the CI issue on your PR pipeline?

Thank you!
