In our customer notification emails, only display the subscription that is about to renew or expire, don't show all subscriptions purchased in the parent order.

Fixes #721

Description

While testing the new Customer Notification feature I noticed that in the table under "Subscription Information", it contained all of my subscriptions that I purchased in the parent/initial order.

For example, I purchased a weekly and an "every 2 days" subscription in the same order, and then processed the "upcoming renewal order" email for just the weekly subscription. When I viewed the email it the subscriptions table contained both of my subscriptions which is not correct:

We don't really have a function available which displays a single subscription info table, therefore this PR introduces a new function to fill this gap. The new WC_Subscriptions_Email::subscription_details() function added in this PR is similar to our existing WC_Subscriptions_Email::order_details() function and can be used to load the subscriptions-info.php template for single or multiple subscriptions.

How to test this PR

Note

To test customer notifications you will need to either:

1. Add return true; at the top of should_send_reminder_email() , or
2. Add define( 'WP_ENVIRONMENT_TYPE', 'production' ); to your wp-config.php file

You will also need a way to test receiving an email. For testing locally, I just use the WP Mail Logging plugin.

1. Go to WooCommerce > Settings > Subscriptions and enable the new Customer Notifications feature
2. Add a weekly and monthly subscription product to your cart and go successfully through the checkout
3. While on trunk, go to the Edit Subscription page for the weekly Subscription and use the actions to run "Send upcoming renewal notification".
4. View the email and notice that both subscriptions are listed under "Subscription Information" the upcoming renewal email ❌
5. Switch to this branch and confirm only the relevant subscription is listed in the email
