[PATCH] ci: ignore rubygems warning in the "Documentation" job

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

A recent update in the Linux VM images used by Azure Pipelines surfaced
a new problem in the "Documentation" job. Apparently, this warning
appears 396 times on `stderr` when running `make doc`:

/usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:10: warning: constant Gem::ConfigMap is deprecated

This problem was already reported to the `rubygems` project via
https://github.com/rubygems/rubygems/issues/3068.

As there is nothing Git can do about this warning, and as the
"Documentation" job reports this warning as a failure, let's just
silence it and move on.

    Fix CI/PR failures in the "Documentation" job
    
    It would probably make sense to apply this to maint, too, as it will
    cause CI failures even if there is nothing actionable to be done to 
    really fix this on Git's side.
