What happended?

When I run "medusa develop" I see my plugin widgets (ex: product reviews table on the products page).

But when I run "medusa build" my plugin's admin widgets do not get bundled into .medusa/server/public/assets. That only has default Medusa admin UI.

Expected behavior

"medusa build" should bundle my plugin's admin UI widgets.

Actual behavior

"medusa build" does not bundle my plugins admin UI widgets
