[villanovachile]

Related to Automattic/jetpack#39466

Proposed Changes

• wpcom-migration was removed from, and duplicator-pro was added to thewpcomsh incompatible plugins. This PR will prevent the installation from dotcom marketplace.

Why are these changes being made?

• To allow the installation of wpcom-migration, which will be required for the upcoming WordPress.com migration plugin
• To prevent the installation of duplicator-pro. Although this pro version likely cannot installed via marketplace, we'll want to make sure there is parity between wpcomsh and calypso.
