Revert #3459

We have a short term workaround thanks to @adityasharad

Short term workaround: please try removing the TAR file /release-images/code-server-amd64-3.10.2.tar (and others like it) from the workspace before running the upload step.

UPDATE: a PR has been merged github/codeql-action#550

So we should be able to re-enable without using the workaround.
