調査結果

本現象（incompatible architecture (have 'arm64', need ' arm64e')）はM1かつXcode 14の環境下でrbenv install 3.1.xを実行した際に発生する
- Ruby 3.1.2と3.1.3は本稿のワークアラウンドで回避できた（その他の3.1.0/3.1.1などは未確認）
macOS 13(Ventura)にアップデートしていない場合はXcodeを13にダウングレードすることで回避できる模様（2023/5/3現在、参考リンク先ではMontereyの場合はXcode 14にアップデートしないことが推奨されている）
Venturaの場合はXcode 13にダウングレードできないため本稿のワークアラウンドで回避する必要がある

対策

ruby-buildのWikiと、Wikiから参考としてリンクされているワークアラウンドのスレッドに記載されている内容に倣う。

ruby-buildを更新する
- brew upgrade ruby-build
  If you have trouble installing a Ruby version, first try to update ruby-build to get the latest bug fixes and Ruby definitions.
  
  First locate it on your system:
  which ruby-build ls "$(rbenv root)"/plugins
  If it's in /opt/homebrew/bin or /usr/local/bin on a Mac, you've probably installed it via Homebrew:
  brew upgrade ruby-build
  https://github.com/rbenv/ruby-build/wiki#updating-ruby-build
Ruby 3.1以上はOpenSSL 3を必要とするためHomebrewでインストールする
- brew install openssl@3 readline libyaml gmp
  Ruby 3.1 and above requires OpenSSL 3:
  brew install openssl@3 readline libyaml gmp export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@3)"
  https://github.com/rbenv/ruby-build/wiki#macos
M1のエラーを回避するためにオプションを付けてrbenv installを実行する
- RUBY_CONFIGURE_OPTS="--disable-install-doc --disable-shared --with-openssl-dir=$(brew --prefix openssl@3)" rbenv install 3.1.2
  Disable building the shared library with RUBY_CONFIGURE_OPTS=--disable-shared
  
  For example, the full invocation you can try to link to Homebrew OpenSSL:
  RUBY_CONFIGURE_OPTS="--disable-install-doc --disable-shared --with-openssl-dir=$(brew --prefix openssl@3)" rbenv install 3.1.2
