brew instructions no longer work

I was following along with the credential helper instructions here

Thew current instructions read but this uses homebrew's short hand for github repo expansion

 brew tap atcr-io/tap
...

Cloning into '/opt/homebrew/Library/Taps/atcr-io/homebrew-tap'...
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
Error: Failure while executing; `git clone https://github.com/atcr-io/homebrew-tap /opt/homebrew/Library/Taps/atcr-io/homebrew-tap --origin=origin --template= --config core.fsmonitor=false` exited with 128.

Presumably this repo used to be hosted on GitHub and since moved to Tangled.

The can be addressed by providing another arg which is the repo to clone.
