This adds a simple workflow to build and push the devcontainer to our github container registry. This would allow us (in a follow-up PR) to use the prebuild devcontainer image from ghcr, instead of needing to first build the image from scratch, which can save quite a bit of time. This a part of #40656. Testing: workflow run in my fork: https://github.com/jschwe/servo/actions/runs/22897536246/job/66435358111 -> created the following image: https://github.com/jschwe/servo/pkgs/container/servo%2Fdevcontainer-ubuntu --------- Signed-off-by: Jonathan Schwender <schwenderjonathan@gmail.com> Signed-off-by: Jonathan Schwender <55576758+jschwe@users.noreply.github.com> Co-authored-by: Sam <16504129+sagudev@users.noreply.github.com>
