Revert "Merge pull request #27686 from koic/friendly_bigdecimal_inspect"

Browse source 
The exact inspect output of a BigDecimal is out of scope for what we're trying
to communicate about `dup` and `duplicable?` here.

Adding two examples distracts is disctracting, so keep the docs from before
since our minimal version is Ruby 2.2.2.
