feat(installer): implementation of snippet config getter

[lauramargar]

Pull request template

Provide a method InterfaceX.getSnippetConfig() that returns the init params of the snippet for both cases of initialization:

• window.initX
• InterfaceX.init()

Customers, kams, devs, etc... are always asking us how to get the snippetConfig configuration of any setup. With this new method they can obtain the configuration quickly and easily, regardless of the way they initialized the project.

If you run the serve script in your local and run InterfaceX.getSnippetConfig() in the console of the devtools, you should obtain an object with the snippetConfig configuration.
