Docker-only dev setup

Use temporary container with current directory volume:

$ docker run --rm -it -v $PWD:/app -w /app mcr.microsoft.com/dotnet/sdk:8.0 bash
# dotnet build aoc2023.csproj
# dotnet test --logger "console;verbosity=normal" aoc2023.csproj
# dotnet test --logger "console;verbosity=normal" aoc2023.csproj --filter aoc2023.day2

$ docker exec -it -w /workspaces/$(basename $PWD) <container-name> bash
# dotnet test --logger .........
