git commit -m 'fix: Ensure containers are tagged by release tag

This commit fixes issue filecoin-project#934 where the container publishing CI workflow
only tagged containers by commit SHA and not by the release tag.

The primary issue was an incorrect nesting of the `workflow_run` trigger
within the `push` trigger in the `.github/workflows/publish-ghcr.yml` file.
This prevented the workflow from being correctly triggered upon the completion
of the `Releaser` workflow, which is responsible for creating Git tags
and GitHub releases.

This change corrects the workflow trigger syntax, ensuring that the
container build and publish workflow runs after a release is made,
allowing it to use the semantic version tag for the container image.
