Image version and build link

Failed build: https://github.com/traversaro/github-actions-brew-update-upgrade-check/actions/runs/1308387900 .

Is it regression?

Yes, latest working version https://github.com/traversaro/github-actions-brew-update-upgrade-check/actions/runs/1306111456 .

Expected behavior

I would expect the update to finish correctly with a 0 return status of the command.

This is my fault but should have already been fixed shortly before this issue was opened.
