setup-ruby: Bundler install appears broken on Ruby 2.2

Ensure the following before filing this issue

• I verified it reproduces with the latest version with - uses: ruby/setup-ruby@v1 (see Versioning policy)

• I tried to reproduce the issue locally by following the workflow steps (including all commands done by ruby/setup-ruby, except for Downloading Ruby & Extracting Ruby), and it did not reproduce locally (if it does reproduce locally, it’s not a ruby/setup-ruby issue)

Are you running on a GitHub-hosted runner or a self-hosted runner?

GitHub-hosted runner

Link to the failed workflow job (must be a public workflow job, so the necessary information is available)

Any other notes?

This has failed in multiple projects, and appears to be a general issue with Ruby 2.2. Here’s another example: https://github.com/jeremyevans/sequel/actions/runs/4723218962/jobs/8378878032

Installation of bundler works locals:

$ gem22 install bundler -v '~> 1.0'
Fetching: bundler-1.17.3.gem (100%)
Successfully installed bundler-1.17.3
1 gem installed
$ ruby22 -v
ruby 2.2.10p489 (2018-03-28 revision 63023) [x86_64-openbsd]
$ gem22 -v
2.4.5.5
