This change introduces a Dockerfile to the devcontainer configuration
that removes the broken Yarn repository from `/etc/apt/sources.list.d/`.
This prevents `apt-get update` from failing due to an expired or missing
GPG key for the Yarn repository.
Fixes#3487
I added a [Remote Development
Containers](https://code.visualstudio.com/docs/devcontainers/tutorial)
in Visual Studio Code (VSCode).
Lots of people like to develop in Containers to have a clean system.
With this PR, it is possible to work with al-folio without any
installation (except for VS Code, its Remote Dev Container extension,
and Docker).
Once you've opened the `al-folio` repository, a prompt will appear
requesting to reopen the project within a container.

Upon doing so, Jekyll will automatically start within the container and
prompt you to open the website's preview sidebar directly in VSCode or
using your Browser. Additionally, it installs extensions for `liquid`
and Prettier (`npx prettier`). Files are formatted using
`al-folios`-prettier settings (`.prettierrc`) to streamline pull request
submission.
Additionally, the performance seems to be much better compared to the
`docker-compose`setup, see #2333.
