[CI] Add embroider-safe scenario (#1157)

* empty

* add embroider-safe, embroider-optimized ember-try scenarios

* deduplicate yarn

* add resolution for @ember/test-waiters because 3.0.1 (reqd by ember-a11y-testing) is not embroider compatible

* yarn deduplicate

* add @ember/string

* add @ember/string v3

* remove embroider pkgs from package.json

* workflow: set fail-fast to false to allow all ember-try to complete

* drop embroider-optimized from ember-try scenarios

* downgrade glimmer/component to v1
