Rebuild for https://fedoraproject.org/wiki/Changes/Ruby_4.0

BSD and MIT needs to be identified under SPDX - both have more options
for UCD see https://gitlab.com/fedora/legal/fedora-license-data/-/issues/30

This is part of https://fedoraproject.org/wiki/Changes/SPDX_Licenses_Phase_4

Note that this is an SPDX identifier, but it still needs to be migrated to the proper identifiers in the fedora-license-data set.

If there will be no comments in two weeks, I will merge this.
