ci: Use forked docker-cache with fix for Bash path

  The `ScribeMD/docke-cache` Github action we use to cache the
  `cozy-app-dev` docker image does not properly run on Github Actions'
  macOS images as it expects Bash to be available at `/usr/bin/bash` but
  Bash is not available by default and Homebrew installs it in a
  different path as `/usr/bin` is read-only.

  To make this action work for us, we forked it to add a `bash` input
  that accepts a string specifying the Bash path to use.
  We'll use our fork until we can get the upstream project to be fixed.
