[FR] chore(dx): setup karakeep to be able to spin up dev containers

Describe the feature you'd like

Inspired by Immich, we could setup karakeep to be able to spin up GitHub dev containers, so that users can easily and quickly start a dev environment on vscode and/or GitHub Codespaces.

Describe the benefits this would bring to existing Karakeep users

While it is almost the same thing as a docker compose based local dev setup, the key difference with a dev containers setup allows for us to spin up Github Codespaces, which is surprisingly useful in unexpected scenarios (speaking from personal experience lol)

Can the goal of this request already be achieved via other means?

Yes. docker compose up and sh start-dev.sh can fulfill the local dev requirement, but dev containers will have more synergy with GitHub Codespaces.

Have you searched for an existing open/closed issue?

• I have searched for existing issues and none cover my fundamental request

Additional context

We have to decide if we will still keep/maintain the docker compose based local dev setup, if we decide to go ahead with this.
