New release for Ruby 3.2

[hsbt]

@kou

👋 Can you cut the release from master or development branch for the Ruby 3.2 release? We have a plan to 3.2.0-rc1 at 12/5 or 12/6 and the final release at 12/25.

We synced the master branch of csv, fiddle, rexml, rss, stringio and strscan. They're also not released version. Can you also handle them? Thanks.

Ah, rexml and rss are already bundled gems. It's unnecessary to release at this time.

OK. I'll do it. It may not be finished for 3.2.0-rc1 but must be finished for 3.2.0.

csv: Done.

fiddle: Done.

stringio: Done but we may need to release one more version: https://github.com/ruby/stringio/pull/26

strscan: Done.
