Generate pattern options code based on option values set in the demo controls panel.

[Eoic]

Show pattern creation and configuration object based on the values set in the demo controls panel so that a user could copy and paste the working implementation. For example,

const pattern = new PerlinNoisePattern({
    octaves: 4,
    frequency: 0.05,
    lacunarity: 2,
});

const ascii = new ASCIIGround()
    .init({
        canvas,
        pattern,
        {
            color: "#20FBCA",
            backgroundColor: "#FF00FA",
            characters: ["1", "+", "#", "-"],
        }
    })

Acceptance criteria:

1. Code is shown and updated when control values change.
2. There is a button to copy the generated code.
3. Pressing the copy button alongside the code block copies the code to the clipboard.
