Subject: [PATCH] [ruby/rubygems] Cover cooldown outdated annotation and update
 error path

Adds three E2E checks against the v2 cooldown artifice: the negative
CLI value is rejected at parse time, `bundle outdated --cooldown` tags
the latest-but-cooled version in both table and parseable output, and
`bundle update --cooldown 99999` surfaces the cooldown hint when every
candidate is filtered. These were the remaining coverage gaps called
out in the adversarial review.
