[kotlin] cleanup: remove unused plugin aliases from content modules (IJPL-207059)

Since other plugins aren't supposed to declare dependencies on these content modules, the content modules shouldn't define plugin aliases. This is because even after we make content modules private by default (see IJPL-207059), a module defining a plugin alias inside can still be referenced via that alias.

There are no usages of these aliases in the monorepo and plugins from the Marketplace, so they can be safely removed.
