Adds a "Manage suggestions" link to the product list metabox, linking to settings.

How to test the changes in this Pull Request:

1. Edit a product. Scroll down to metabox, click Get more options tab.

Note that the link destination (the new settings section) is implemented in separate PR #23218 .

Note that I've added another alias for this suggestion, as the original one was misleading / confusing. I'm renaming it in the json data, but I've got both here. In future we can remove product-edit-empty-footer-browse-all.

Similarly to @kloon 's point over at #23218, should this link be shown only to admins/users who actually can change this setting, to prevent confusion?

@peterfabian the suggestions areas are only shown to users with the capabilities to install plugins, so these links will only be present when the suggestions are visible.

Thanks Rua, this is testing out well for me. Let's coordinate merges to navigate all the merge conflicts accordingly.
