Introduce CI with GitHub Actions Add CI using GitHub Actions and GitHub Packages: * This moves our Linux build containers into GitHub Packages; we will identify the most recent commit that updated the docker descriptions, and then look for a docker image in libgit2's GitHub Packages registry for a container with the tag corresponding to that description. If there is not one, we will build the container and then push it to GitHub Packages. * We no longer need to manage authentication with our own credentials or PAT tokens. GitHub Actions provides a GITHUB_TOKEN that can publish artifacts, packages and commits to our repository within a workflow run. * We will use a matrix to build our various CI steps. This allows us to keep configuration in a single place without multiple YAML files.
