Change dependency for commerce_checkout

Now the dependency is the commerce_cart module. It's not enough when installing the commerce_quick_purchase as the base module.

To reproduce

Create a simplytest.me site: https://simplytest.me/project/commerce?add[]=readmehelp&add[]=commerce_q...

Go to admin/modules page, type purchase in the textfield to find the Commerce Quick Purchase module, tick in the checkbox and then press the Install button. Everything seems OK, almost all the Drupal Commerce modules and README Help module are installed. The issue appears when you try to set up redirection to the checkout page on the Quickly add any product to cart block settings page. Just because the commerce_checkout module remains not installed with the commerce_cart dependency in the commerce_quick_purchase.info.yml file.

Solution

Change dependency for commerce_checkout module allowing users to install everything what is needed just ticking the Commerce Quick Purchase module's checkbox.
