In the previous versions, append gem: --no-document
for c:\ProgramData\gemrc, but it does not work as expected
because the default gemrc content is different as we thought.

So, we should override explicitly by gem: --no-document here.

  C:\>type c:\ProgramData\gemrc
  # This is the system wide config file for Rubygems.
  # It is generated by RubyInstaller as a security measure.
  # Feel free to add any rubygems config options as described on:
  #    https://docs.ruby-lang.org/en/3.1/Gem/ConfigFile.html
  # But do not delete this file as otherwise it could be hijacked by
  # another user in a multi-user environment.

  {}
  gem: --no-document

  C:\>echo gem: --no-document > c:\ProgramData\gemrc

  C:\>type c:\ProgramData\gemrc
  gem: --no-document
