Even though it's a bundled gem and not a default gem, it would be worthwhile backporting the fix for CVE-2025-58767 (https://www.ruby-lang.org/en/news/2025/09/18/dos-rexml-cve-2025-58767/).

Ruby 3.4 PR: https://github.com/ruby/ruby/pull/14795
Ruby 3.3 PR: https://github.com/ruby/ruby/pull/14796

I'm not sure what to do for Ruby 3.2. It's a security fix so it qualifies for a backport, but there's other changes included in a version bump. Do we need a rexml 3.3.9.1?

I am a maintainer of REXML.
Ruby 3.2 is subject to security fixes, so I believe an update is necessary.

I created this PR.
