How to test the changes in this Pull Request:

Using WP CLI, try running:

wp eval "print_r( WC_Tracker::get_tracking_data()['settings'] );"

At the end of the output, you should see the new Marketplace suggestions and MCM-related options, looking something like this:

    [show_marketplace_suggestions] => yes
    [multichannel_marketing_enabled] => no

Each option should have the value yes if the corresponding option in WC settings is enabled, or no or an empty value if the corresponding option in WC settings is not enabled.

Hi @jorgeatorres, this is a tiny PR, would you mind taking a look and giving it a green light if it's ready, so I can update the project to completed? (But not shipped until WC 7.6 in mid-April).
Thanks! 🙇🏻
