Make the width of "Back to Store" and "Back to Website" buttons consistent with other buttons in order confirmation page

[navaneethkp36]

What? Why?

• Closes Order confirmation page: inconsistent width buttons "Back to Store" and "Back to Website" #13651

The width of "Back to Store" and "Back to Website" buttons in order confirmation page are not consistent with the other buttons. This is fixed in this PR.

Code changes:

• Removed unwanted divs .columns.small-12.medium-5 and .columns.show-for-medium-up.medium-1   which were causing this styling issue
• Changed .columns.small-12.medium-6 to .columns.small-12.medium-3 for "Back to Store" and "Back to Website" button divs to make it consistent with other buttons

After:

What should we test?

• As a hub, on the Shop preferences tab, toggle the option "Customers can change / cancel orders while order cycle is open"
• As a hub, make sure you have the Address field filled in, in the Contacts tab
• As a customer place an order
• On the order confirmation page, verify the width of the buttons "Back to Store" and "Back to Website" are consistent with the other buttons.
• Check the button size for both desktop view and mobile view
