Intend to retire rubygem-rspec2 series on Fedora 35

[Mamoru TASAKA]

Hello, ruby-sig folks:

Since rspec 3.0.0 is released on 2014/Jun (almost 7 years ago),
Fedora's rubygem-rspec is upgraded to 3.x on Fedora 22 era, and compat package
rubygem-rspec2 is introduced.

Since I think enough time is already passed for packages to migrate to
rspec 3.x and actually:
----------------------------------------------------------
$ dnf repoquery --arch=src --repo=koji-35-source --whatrequires
"rubygem(rspec2)"
rubygem-database_cleaner-0:1.7.0-5.fc34.src
rubygem-nifti-0:0.0.2-14.fc34.src
rubygem-rspec2-core-0:2.14.8-11.fc34.3.src
rubygem-rspec2-expectations-0:2.14.5-10.fc34.7.src
rubygem-rspec2-mocks-0:2.14.6-6.fc34.6.src

$ dnf repoquery --repo=koji-35 --qf
'%{name}-%{epoch}:%{version}-%{release}\t%{SOURCERPM}' --whatrequires
"rubygem-rspec2"
rubygem-json_spec-0:1.1.5-9.fc34	rubygem-json_spec-1.1.5-9.fc34.src.rpm
rubygem-rspec2-doc-0:2.14.1-14.fc34	rubygem-rspec2-2.14.1-14.fc34.src.rpm
----------------------------------------------------------

currently, very few packages depend on rubygem(rspec2).

* rubygem-json_spec actually has dependency: "(rubygem(rspec) >= 2.0 with
rubygem(rspec) < 4.0)"
   so this is okay
* For rubygem-nifti, I successfully migrated this to use rspec-3.x locally, so (unless
someone
   objects), I will push changes to use rspec-3.x
* For rubygem-database_cleaner, current upstream newest is 2.0.1, which is released on
2021/Feb,
   so the latest one is perhaps using rspec-3.x, I guess.

so I intend to retire rubygem-rspec2 series, perhaps in two weeks, or if someone objects,
at least I intend to orphan rubygem-rspec2 series on Fedora 35.
