rubygems not installing v1.0.4

[chrishough]

I just noticed the tag on rubygems says 1.0.4 when I install via gem 'sidekiq-failures' however this code repository does not seem to have that tag, and I think rubygems is loading an older version, the 1.0.1 release

➜  backend git:(feature/core-setup) ✗ rbe rails c
Loading development environment (Rails 7.0.4.3)
Ruby 3.2.1-p31
development - (main):0 > Sidekiq::Failures.clear_failures
NoMethodError: undefined method `clear_failures' for Sidekiq::Failures:Module
from (pry):1:in `<main>'
development - (main):0 >

When I install like this, it works just fine, thoughts all?
gem 'sidekiq-failures', git: 'https://github.com/mhfs/sidekiq-failures', branch: 'master'
