I think it's LicenseRef-Fedora-Public-Domain.
First, it does not match any SPDX-known license text.
Second, "CC0 Public Domain Dedication" probably refers to SPDX license CC-PDDC
Third, the <http://creativecommons.org/publicdomain/zero/1.0/>
link refers to
CC0-1.0, a different license from CC-PDDC.
Last, recently I asked a similar case (a public domain dedication with
a fallback to a license)
and Richard Fontana concluded that these kind of texts fall into
In the case of blake2 though there is a copy of the CC0 text in the
COPYING (previously named LICENSE) file in the repository.
