Deprecation of `--no-rdoc` and `--no-ri` options causing installation failure

I encountered an issue while attempting to install pgxn_utils using the command pgxn install pgxn_utils. The installation process failed with the following error:

INFO: best version: pgxn_utils 0.1.4

Upon investigation, it appears that the pgxn_utils package is still using the deprecated --no-rdoc and --no-ri options, which were removed from RubyGems 5 years ago in favor of the --no-document option.

Considering that these options were deprecated 12 years ago and removed 5 years ago, the usage of pgxn_utils is currently incompatible with newer versions of Ruby and RubyGems.

I would like to propose addressing this issue by updating the pgxn_utils package to use the current documentation options provided by RubyGems. This will ensure compatibility with the latest versions of Ruby and prevent installation failures.

Updating the package to use the --no-document option instead of the deprecated --no-rdoc and --no-ri options. This will allow users to successfully install pgxn_utils with the latest versions of RubyGems. I believe addressing this compatibility issue will greatly benefit users who wish to install and utilize the pgxn_utils package with the latest Ruby and RubyGems versions.

Hey @guedes, I'm working on a PGXN presentation and was hoping to demo utils, but they don't build for me due to this issue. I'm sure a bunch has changed over the years; do you think you'll have the bandwidth soonish to update pgxn-utils for these changes, for Ruby 3, etc.? Thanks!
