Upload correct container image (#3)

The devcontainer/ci action uploaded the devcontainer used to develop the S-CORE devcontainer. But it should have uploaded the S-CORE devcontainer instead.

According to https://github.com/devcontainers/ci/blob/main/docs/github-action.md#inputs `subFolder` should specify the correct path to the container.
