perldiag: Remove ‘The %s feature...’

The idea when this was added was for ‘use feature’ to warn when
an experimental feature was enabled.  Things didn’t turn out that
way.  Only lexical subs follow that wording, and they have their
own entry in perldiag, so this one is unnecessary.

-(S experimental) This warning is emitted if you enable an experimental

-to use the feature, but know that in doing so you are taking the risk
