Fix #13315. Mobile 'Payments methods' step looks bad on mobile

[Frodigo]

Description

Fixes for bad looks of step-title in the payment methods section at the checkout.

I added padding to the .step-title element such as padding in the other elements in this section. I used @checkout-payment-method-title-mobile__padding variable.

I apply my changes to both Magento themes (blank & luma)

Fixed Issues (if relevant)

1. Mobile "Payment Methods" step looks bad on mobile #13315: I "Payment Methods" step looks bad on mobile

Manual testing scenarios

1. Go to frontend, add some product to shopping cart on mobile (or in iphone emulation mode on chrome)
2. Go to Checkout, fill "shipping" step, click "Next" button
3. See "Payment Methods" block
4. Step title heading "Payment Method" should be correctly aligned with other elements in this section
