Fix multi WizardStep

[ron-tayler]

Don't work:

@WizardStep(2)
@WizardStep(3)
async invalidInput(@Ctx() ctx: WizardContext) {
  await ctx.reply('❌ Invalid Format. Please, try now.');
}

Work, but bad code style:

@WizardStep(2)
async invalidInput2(@Ctx() ctx: WizardContext) {
  await ctx.reply('❌ Invalid Format. Please, try now.');
}

@WizardStep(3)
async invalidInput3(@Ctx() ctx: WizardContext) {
  await ctx.reply('❌ Invalid Format. Please, try now.');
}

Add in this Pull-Request, good style:

@WizardStep(2, 3)
async invalidInput(@Ctx() ctx: WizardContext) {
  await ctx.reply('❌ Invalid Format. Please, try now.');
}
