Add temporary metadata update step to Cypress flow (#1173)

* Add temporary metadata update step to Cypress flow

Also updates baselines

* Run Cypress action as root

This allows us to install ExifTool. UID `1001` seemed to be used so
Firefox will run, which we're not currently doing.

* Run Cypress action as root

* Add checkout as safe directory
