feat(PaginatedMessage): add method to update pages after response

[killbasa]

Adds a method to update page content after PaginatedMessage has run, allowing more interactivity when handling buttons.

Example:

run: async ({ handler }) => {
    const value = Math.floor(Math.random() * 10);

    await handler.updateCurrentPage({
        embeds: [
            new EmbedBuilder().setDescription(`${value}`)
        ]
    });
}
