fixup! Add workflow for apt-get release

Upgrade 'actions/github-script' from v3 to v6 to silence the Node.js 12
deprecation warning. Note that this also includes an update to how the
'github' object is accessed in the script ('github' -> 'github.rest')
due to a breaking change introduced in v5 [1].
