3. See not renderd embed

What is current behaviour

Embedded gist will not be renderd.

What is the expected behaviour

Embedded gist should be renderd.

Other relevant information

This is not working because the type of quotes are not supported. The default prettier configuration changes the '' to "". And if you have auto format toggled on, you're not be able to save the file working.

As per conversation at https://discord.com/channels/713647066802421792/719155521109884978/855738415399043082, double quotes don't work while single quotes do, but I haven't tried this particular feature to confirm.

I imagine there's an easy fix for it.
