Upgrade to Ruby 3.3

[sethboyles]

In light of the impending Ruby 3.2 EOL (2026-03-31) we need to upgrade Ruby.

Upgrading to Ruby 3.3 is complicated by this Bundler bug: ruby/rubygems#8217, and this PR gets around this bug by using gem fetch bundler -v GEMFILE_LOCK_VERSION in prepackaging and installing from the local bundler gem copy during packaging.

Every jobs which uses the CCNG job will check if the right bundler gem version is installed, and if not, install from the local copy.

(another potential solution is packaging git on the VMs)

I'm putting forth this solution as opposed to upgrading to Ruby 3.4 directly (which would skip the broken Bundler version), as Ruby 3.4 will require more syntax changes and we'd be more at risk of encountering gems that are incompatible with 3.4, notably the unmaintained Fog gems. Compare the Ruby 3.3 changeset to the old Ruby 3.4 changeset from a year ago.

Tasks before this is safe to merge:

• Figure out how to avoid Bundler bug: Bundler 2.5.17 breaks bundling vendored gems from git, when git is not installed during bundle install --local ruby/rubygems#8217

  • Even on online/non-airgapped environments, this issue arises despite the fact that Bundler is supposed to check the Gemfile.lock and install the configured version

• Run units on various fog gems on Ruby 3.3 (and make PRs if necessary)

  • fog-local
  • Azure
  • S3/S3 compatible
  • GCS
    • They run units against 3.3 in their pipeline: https://github.com/fog/fog-google/commits/master/
    • Integration tests aren't running? Might be a concern as they recently had a bug that broke signed urls
  • Aliyun ?
  • fog-core
    • They test Ruby 3.3 in CI https://github.com/fog/fog-core/actions/runs/20576940808/job/59095969099
  • fog-json
    • They don't run CI for this, and I have the same tests failing for Ruby 3.2 and Ruby 3.3

• CATs/BARAs on Blobstores for Fog coverage

  • Local
  • Azure
  • S3/S3 compatible
  • GCS
    • CATS
    • BARAS
  • Aliyun ?
