Ember: Fix broken import

[yannbertrand]

Following #21435.

Hopefully closes #20653

What I did

Ember recommends to use @glimmer/component rather than @ember/component. I switched the import and the package.json accordingly. I believe ember itself somehow import @glimmer/component so maybe the peer dependency is not needed. I couldn't launch the project myself locally so let's wait for CI check.

How to test

• Create a fresh app Ember

npx --package ember-cli ember --version #ember-cli: 4.11.0
npx --package ember-cli ember new ember-quickstart

• Check Ember app works fine

cd ember-quickstart
npm start

• Install this storybook PR for Ember

npm install --save-dev yannbertrand/storybook#main

• Init Storybook

npx storybook --version #6.5.16
npx storybook init

• Hopefully this command now works and render something

npm run storybook

⚠️ New author

A new npm collaborator published a version of the package for the first time. New collaborators are usually benign additions to a project, but do indicate a change to the security surface area of a package.

Scrutinize new collaborator additions to packages because they now have the ability to publish code into your dependency tree. Packages should avoid frequent or unnecessary additions or changes to publishing rights.
