What OS and OS version are you experiencing the issue(s) on?

MacOS Catalina

What version of graphql-playground(-electron/-middleware) are you experiencing the issue(s) on?

1.7.21

What is the expected behavior?

saveSettings handler should allow for settings to be saved...

What is the actual behavior?

SaveSettings handler should fire correctly and save my settings...

What steps may we take to reproduce the behavior?

install latest package, launch playground, open dev tools, go to settings, change any settings press command+s or click saveSettings button . saveSettings handler is not a function.
If i hard code in version 1.7.9 (first version i tested) into the script tag inside the render-playground-page.js file the error is resolved.

@binoy14 @beeman is this something we forgot to test in the last release? Hmmm

In fact, I can't seem to find when this was last set up properly in master. looks like this prop handler has been missing for a while, looking at PlaygroundWrapper.tsx more closely
