It seems that the version of node has been published for actions/node-versions, but there's likely still some deploying that is in progress or needs to happen.

Looks like things are back green again. I reverted the merge commit wholesale, but I'm not opposed to keeping the changes around introducing a name for each value. Though those change anyway when we change the version in the matrix, so it doesn't solve the same problem.

Thanks @desrosj for remembering to do this 😄
