[llvm] workflows/build-ci-container: Fix container push (PR #125610)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/125610

After the changes in 89001d1de8ecf03c8820594ea03345b99560272a, the container pushes failed, because it was attempting to push the same container twice.  This fixes the sed expression used to push the :latest alias for each container.
