Use Map instead of JSObject to update window.intercomSettings

Using the JSObject was working in debug mode. But in the release mode it throws the following error during build.

The compiler crashed: Reference to dart:_js_types::JSObject::@methods::|staticInteropFactoryStub is not bound to an AST node. A procedure was expected

This is the documentation of JSObject under js_interop (Flutter 3.16.9)

/// This is the supertype of all JS objects, but not other JS types, like
/// primitives. This is the only allowed `on` type for inline classes written by
/// users to model JS interop objects. See https://dart.dev/web/js-interop for
/// more details on how to use JS interop.
