3.5.1

Enhancements

• Dropped custom popper.js & tooltip.js bundling in favor of ember-auto-import.
• Support for Ember 3.28 & 4.0.0
  • There are still some lingering deprecations
• Support for Embroider

CI changes

• Upgrade to ember-qunit v5
• Dropped Node < 12 support
• Upgrade a bunch of outdated test dummy app dependencies
• Embroider CI support (#429, thanks @thoov !)

Note: This is the same set of changes as 3.5.0, which I accidentally tagged wrong, so there is a deprecated release in NPM for that version.
