Official Devcontainer feature and template

Community members have tried building a devcontainer https://github.com/haskell/docker-haskell/issues/41

The result at that time was: https://github.com/microsoft/vscode-dev-containers/tree/main/containers/haskell

However, the repo `microsoft/vscode-dev-containers` is now archived. [The Microsoft team split this repository into the Devcontainer feature and the Devcontainer template.](https://github.com/microsoft/vscode-dev-containers#:~:text=For%20new%20Templates/Features%2C%20you%20can%20now%20self%2Dpublish%20and%20optionally%20make%20them%20visible%20in%2Dtool%20by%20following%20the%20steps%20one%20of%20the%20quick%20start%20repositories%3A%20Templates%20quick%20start%2C%20Features%20quick%20start.%20No%20need%20to%20submit%20a%20PR%20here%20anymore.)

So now we may need a Haskell Devcontainer feature and a Haskell Devcontainer template.

In [this list](https://containers.dev/features), there is already a [haskell feature](https://github.com/devcontainers-contrib/features/tree/main/src/haskell). Has the haskell community reviewed this devcontainer feature?

And there is currently no haskell devcontainer template available yet.
