* chore: 🤖 replace CopyButton usage with Hds::Copy::Button * chore: 🤖 remove ember-cli-clipboard * test: 💍 fix test by stubbing writeText The hds copy button uses the browser clipboard api. The writeText api can fail if the window is not active. This does not happen in practice because the window has to be active to be clicked by the user. But in tests with synthetic triggers this can fail. Stubbing the writeText method is also how hds tests their component: https://github.com/hashicorp/design-system/blob/990981b5741f9a6bf28d100c330b7865ba74e506/showcase/tests/integration/components/hds/copy/button/index-test.gts#L20
