ubuntu 20.04 linux releases are failing

Run actions/download-artifact@v1
Downloading artifact 'bazelfe-linux-ubuntu-20.04' to: '/home/runner/work/bazelfe/bazelfe/downloads'
Error: An Artifact with name "bazelfe-linux-ubuntu-20.04" was not found.
Error: Exit code 1 returned from process: file name '/home/runner/runners/2.312.0/bin/Runner.PluginHost', arguments 'action "GitHub.Runner.Plugins.Artifact.DownloadArtifact, Runner.Plugins"'.

see in: https://github.com/bazeltools/bazelfe/actions the release actions from main have been failing.

I took a quick glance, but it seemed like the ubuntu 20.04 artifact was uploaded by the previous job. It could be some issue with ubuntu 20.04 deprecation.
