How to update dependencies

Go to https://github.com/input-output-hk/plutus-apps/tags and take note of the latest plutus-starter-devcontainer tag and its commit hash.
Update the tag and/or hash in the following files:
- .devcontainer/devcontainer.json
- nix/sources.json
- nix/pkgs/haskell/haskell.nix
- cabal.project
Copy over most of https://github.com/input-output-hk/plutus-apps/blob/main/cabal.project into cabal.project
Copy over the sha256map values from https://github.com/input-output-hk/plutus-apps/blob/main/nix/pkgs/haskell/haskell.nix into nix/pkgs/haskell/haskell.nix (but leave the first line that you just changed in step 2). To get the right hash value for plutus-apps, change one digit, then run nix-shell. You will get an error that shows the correct hash.
It’s likely that the code for the guessing game needs to be changed; luckily, you can copy the source from https://github.com/input-output-hk/plutus-apps/blob/main/plutus-playground-server/usecases/Game.hs roughly, and it should work.
Test the different parts:
- VSCode
  - You need to make sure to rebuild the image
  - Then, once in VSCode, do cabal build and cabal test, and then make sure HLS works
- nix
  - nix-shell
  - cabal build/cabal test
