If you go to the package overview page, in the upper right corner you have a link to the publishing history. According to https://launchpad.net/ubuntu/+source/grip/+publishinghistory it was removed during the 23.04 cycle, and it looks to be the same issues which got it removed from Debian testing. Presumably these two issues need to be resolved and then a newer version would be autosynced from Debian to Ubuntu at a future point.
