[Qute] Custom default value is ignored in {config:boolean } rendering

[fbricon]

Describe the bug

According to https://quarkus.io/guides/qute-reference#config, when you write {config:boolean('quarkus.foo.boolean') ?: 'Not Found'}, I was expecting it displays Not Found if quarkus.foo.boolean is not defined. But NOT_FOUND is rendered instead

Expected behavior

Display the user-defined default value

Actual behavior

Displays hard-coded NOT_FOUND

How to Reproduce?

Just paste {config:boolean('quarkus.foo.boolean') ?: 'Not Found'} in https://github.com/quarkusio/quarkus-quickstarts/blob/main/qute-quickstart/src/main/resources/templates/hello.html, run the app and access http://localhost:8080/hello
