Fix edit_config multiline commands on IOS (#35375)

* Fix edit_config multiline commands on IOS

The current code for multiline commands in IOS is broken: If you
pass a dict containing a command, prompt and answer it is seen
later as unicode string, but if you do a json.loads it fails
as the keys/values are enclosed in single quotes but JSON requires
double quotes.

Fixes #23539

* Fix pep8

* Use ast literal_eval

It's safe to use, as it is just for types and wont execute arbitrary code.
