Subject: Define BuildKite pipelines in Nix

After a handful of failed attempts to run lint-secrets.sh due to a missing
`git-secrets` executable on my git server, I decided that now was a good time to
use Nix to define my BuildKite pipelines.

TL;DR:
- Delete ci/scripts directory
- Define ci/pipelines/{briefcase,socrates}.nix

Outside of this repository:
- I logged into my admin account at git.wpcarro.dev and changed my Gitea
  post-receive hook to trigger the briefcase pipeline
- I logged into my BuildKite account, deleted my build-briefcase pipeline,
  created a new briefcase pipeline that called:

  ```shell
  nix-build -A ci.pipelines.briefcase -o briefcase.yaml
  buildkite-agent pipeline upload briefcase.yaml
  ```

One day I will audit all of my ad-hoc, non-mono-repo activity (like the steps I
listed above) and attempt to fit everything herein... one step at a time,
though!
