Deprecation: registerPlugin is deprecated

[IgnaceMaes]

Hello 👋

In an Ember 3.28 app running using ember-sortable v3.0.0 I'm getting the following deprecation warning during the build. I didn't see an issue for it yet on this repository but let me know if this is tracked somewhere else!

[Babel: ember-sortable > applyPatches]DEPRECATION: registerPlugin is deprecated, please pass plugins directly via `compile` and/or `precompile`. [deprecation id: template-compiler.registerPlugin]
