[feat] add option to edit a config

[jdwilkin4]

I am working on add the relational database questions and noticed that I made a mistake in the config.

I noticed there wasn't a way to edit a current config here

It would be nice to have an edit button instead of removing that completely and creating a new config

I am not going to prioritise this much. It is a nice-to-have.
