Task/22.0 release notes

[joshheald]

Update release notes for 22.0

This update adds the option to set different notification preferences for each store. In Orders and Products, your filters stay around as you move through the app, and we've fixed a crash that could happen when you choose pictures for your products. Payments is improved too, with support for Puerto Rico in WooPayments, and better accessibility.
