Hopefully useful information: the download may be failing because of an expired SSL certificate on https://yt-dl.org
The workflow is failing for me with the same error as above (failing to download youtube-dl). Have just tried to download it using the instructions in the GitHub readme at https://github.com/ytdl-org/youtube-dl#installation , and curl tells me that the ssl certificate for https://yt-dl.org/downloads/latest/youtube-dl has expired.
For politeness sake:

(don't currently have brew installed, that's my next troubleshooting step, this isn't yet a request for help!)
