[UI] Quiz Settings

[Nefariusek]

As a user, I want to have the ability to change the settings of the quiz.

Acceptance criteria

Verify, consult and update before starting.

• 1st Section is labeled "Category", Radio buttons are visible inside, labelled "Cats" and "Dogs"
• 2nd Section labelled "Number of Questions". Input field is visible and the user can enter a positive number of questions (up to 20)
• 3rd Section is labeled "Question Type". Radio buttons are visible inside, labelled "Open" and "Multiple Choice"
• Button is labelled "Start Quiz".

Additional notes

• Follow the UI project from miro.
• Store user's settings in an object.
• This functionality should be stored in a separate .js file.
• For now Start quiz will show alert() with selected settings.
