Test for and document plugin compabilities

[jeffpaul]

Is your enhancement related to a problem? Please describe.
We often get questions about whether Distributor works with a specific plugin (e.g., WooCommerce). We also get issues opened for oddities when using Distributor with other plugins. We don't currently do any testing for incompatibilities against major plugins in the ecosystem nor do we maintain a listing of known incompatibilities (or compatibilities).

Describe the solution you'd like

• Cypress e2e test suite with instances of Distributor and another major ecosystem plugin to help flag issues in our builds/releases (e.g., WooCommerce, Page Builders, Polylang, WPML, Ninja Forms, etc.)
• Documentation on plugins with known incompatibilities (noting plugin versions)
• Documentation on plugins that are known to be compatible (noting plugin versions)
