[5.x]: Donation not available

What happened?

Description

After upgrading from Craft 4, adding donations to the cart doesn't work anymore, neither in the frontend nor in the backend.

In the frontend, when I submit the the donation form to commerce/cart/update-cart nothing happens, the cart is still empty, also no error message.

In the backend it's also not possible to add a donation to an order via the "Add a line item" functionality on the order detail page. The donation line item cannot be selected and the "Available?" column has no checkmark. When the order site is not my primary site I don't even see the donation item in the list 🤔

I found that the "getIsAvailable" method on the Purchasable class returns false because in my database the column "inventoryTracked" of the commerce_purchasables_stores table contains "1" for the entry corresponding to the donation purchasable. Re-saving the donation settings through the backend also doesn't do anything because it skips the current (and in my case only) store when setting the default values.

Steps to reproduce

1. Setup a Craft 4 project with donations
2. Upgrade to Craft 5
3. Try to add a donation to the cart

Expected behavior

After upgrading from Craft 4, it should still be possible to add a donation to the cart.

Actual behavior

It's not possible to add a donation to the cart.
