This reverts merge request !160824

All our CI pipelines already pass for Ruby 3.2, so let's
bump to Ruby 3.2.2 to flush out any other issues that might arise.

Merge branch 'secMaster' into 'master'

See merge request gitlab-org/security/gitlab!2945

Changelog: security

Changelog: changed

Since Ruby 2.7.2 comes with bundler v2.1.4 by default, we need to
upgrade the Gemfile.lock and bump the CI cache keys. We also need to
install bundler v1.17.3 to ensure a smooth transition for other
dependencies, like Gitaly.

Exclude development gems from QA bundle install since debaser doesn't
compile on Ruby 2.7.

Attempt to update google-protobuf for migration-paths

Because the one we were using aren't compatible with
Ruby 2.5.3, and it'll be troublesome to switch Ruby.
Upgrading google-protobuf will be much easier.

All of them will need to be updated for Ruby 2.5.3

We remove oj because we don't really need it and it
doesn't compile on 2.5.3 with that version.

* A change in Ruby (https://github.com/ruby/ruby/commit/ce635262f53b760284d56bb1027baebaaec175d1)
requires passing in the exact required length for OpenSSL keys and IVs.

* Ensure the secrets.yml is generated before any prepended modules are
loaded. This is done by renaming the `secret_token.rb` initializer to
`01_secret_token.rb`, which is a bit ugly but involves the least impact on
other files.

* Reading an invalid OpenSSL::PKey causes OpenSSL to throw OpenSSL::PKey::PKeyError
instead of ArgumentError (https://github.com/ruby/openssl/blob/master/History.md).

Fixes that make this work:

Ruby 2.1.8 is used only on master for now, as this would give
confidance in case this commit has to be reverted.
