Gem commands fail if Windows user have a white space when installed for all users

[HatsuMora]

I reported this issue first in rubygems/rubygems#6288 and they recommended me to also create a issue here.

What problems are you experiencing?

After upgrading from rubygems (gem) from 3.3.3 to 3.4.4 I could not install any gem or run several gem-related commands.
For example gem env.

ERROR: While executing gem ... (Gem::CommandLineError)
Unknown environment option [Rincón]

or gem install rails:
ERROR: While executing gem ... (URI::InvalidURIError)
URI must be ascii only "Rinc\u00F3n".

I tried to investigate the issue myself and find out that there is value.split(" ") on C:\langs\Ruby32-x64\lib\ruby\3.2.0\rubygems\command.rb:79 that will split arguments by white space therefore my user name is being splitter and miss interpreted. This extra arg is set by lib\ruby\3.2.0\rubygems\defaults\operating_system.rb:11. Operating system is setting a default --install-dir and --bindir based on Gem.user_dir.

As a workaround for myself, I added wrapped both paths on ' in operating_system.rb and change the split to @extra_args = value.split(/\s+(?=([^']*"[^']*')*[^']*$)/) in command.rb (split by white spaces that are not between single quotes).

Steps to reproduce

1. Create a windows user that contains a white space on the user path.
2. Install Ruby+Devkit 3.2.0-1 (x64) from Ruby Installer.
3. When asked, install for all users. (Requires elevation)
4. run gem env or gem install rails

What's the output from ridk version?
