[graphiql] defaultQuery with empty string does not result in empty default query

[incompl]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Currently if you set defaultQuery="" you get the commented intro text in the editor by default.

Expected Behavior

I expect the query editor to be empty in this case.

Steps To Reproduce

• Add defaultQuery="" to your GraphiQL component
• Clear localstorage so you don't get your last query shown by default and refresh

Environment

• GraphiQL Version: 3.1.0
• OS: OSX 13.6.1
• Browser: Chrome 120.0.6099.199
• Bundler: Webpack
• react Version: 18.2.0
• graphql Version: 16.6.0

Anything else?

This worked as expected previously. I am upgrading from 1.x to 3.x.
