/**
 * Alerts are meant to provide a way to communicate urgent or important information to users, frequently as a result of an action they took in your app. Alerts are positioned
 * at the bottom of the page. Multiple opened alerts will be added to a queue, allowing users to dismiss them in the order they are provided.
 *
 * @slot [title] - A slot for adding a title to the component.
 * @slot [message] - A slot for adding main text to the component.
 * @slot [link] - A slot for adding a `calcite-action` to take from the component such as: "undo", "try again", "link to page", etc.
 * @slot [actions-end] - A slot for adding `calcite-action`s to the end of the component. It is recommended to use two or fewer actions.
