Pull Request

📖 Description

With the project re-alignment goals (#6955) this change seeks to highlight the use of @microsoft/fast-element as the package the documentation site is now focused on. This is similar to the previous frontpage for v1, however the content has been amended to get the user started on @microsoft/fast-element and states the updated project goals.
