[PATCH -perfbook v2 3/3] Use date as rollback options for glossaries related packages

While discussing about rollback of the array package, array's maintainer
recommended using date as rollback options.

Apply the same approach for rollback of glossaries related packages.
This way, it would be obvious that those packages as of early October
2022 worked fine.
