@ember/test-helpers is trying to import from ember-testing but that is not one of its explicit dependencies

Although the new version is mostly working without this error, it is coming up reliably when the following conditions are met:

• using @embroider/core@3.4.14 (or probably any other version pre 3.4.15, that hasn't Update ember standard modules to include @ember/renderer and @ember/-internals and ember-testing embroider-build/embroider#2075)
• running the build with Embroider and safe mode (optimized is working!)

The root issue seems to be in Embroider, posting this here for visibility.

Seeing that issue in a v2 addon tests when updating from @ember/test-helpers v4.0.2 to v4.0.4 https://github.com/retailnext/ember-bem-helpers/actions/runs/10786506229/job/29913502499

Confirmed that bumping @embroider/core to the lates fixed the issue.
