By disabling line wrap we can consistently predict how it will appear. The longest translation we currently have is 14 characters so this should be fine.
This was broken when upgrading [Foundation](https://github.com/openfoodfoundation/openfoodnetwork/pull/11349). For some reason the button.expand class now sets larger font size and padding, which overrides the button.small class. It's probably a bug but we'll have to work around it.
