Load Wallet Connect SDK from disk in storybook and from binary (QRC) in the app

[stefandunca]

Following on the discussion here #14590 use the QT's flexible mechanism to alternatively load the SDK from disk as proposed by @micieslak.

From the Qt documentation: https://doc.qt.io/qt-5/qml-url.html

The url type refers to a resource locator (like a file name, for example). It can be either absolute, e.g. "http://qt-project.org", or relative, e.g. "pics/logo.png". A relative URL is resolved relative to the URL of the containing component.

Note: When referring to files stored with the [Qt Resource System](https://doc.qt.io/qt-5/resources.html) from within QML, you should use "qrc:///" instead of ":/" as QML requires URL paths. Relative URLs resolved from within that file will use the same protocol.

Based on the QT specifications and given the fact that WalletConnectSDK is loaded from resources in the app we can ensure the SDK is also loaded from resources.
