Subject: [PATCH] Fix Duration doc examples to use message literal syntax

The const, lt, lte, in, and not_in examples in DurationRules showed
string values like "5s", which do not compile for
google.protobuf.Duration option fields. Replace them with message
literal syntax matching the gt, gte, and example docs.

Fixes #499
