Create a Resolver for java.time.ZonedDateTime

[MessiasLima]

Description

The library supports java.time.Instant and java.time.Duration but does not yet support java.time.ZonedDateTime. Adding this resolver will allow users to generate random ZonedDateTime instances as part of their test fixtures.

This follows the existing pattern for Java time resolvers: a JavaZonedDateTimeResolver class implementing TypeResolver, registered in SomeConfig.buildResolvers, and covered by unit tests.

Scope

• In scope: JavaZonedDateTimeResolver, registration in SomeConfig, and unit tests.
• Out of scope: Kotlin kotlinx.datetime types, OffsetDateTime, or other java.time types.

Acceptance criteria

• GIVEN a java.time.ZonedDateTime type
  WHEN some<ZonedDateTime>() is called
  THEN a valid ZonedDateTime instance is generated
• GIVEN JavaZonedDateTimeResolver
  WHEN it resolves a value
  THEN the generated instant falls within a reasonable range (e.g., 1970 to 2100)
• GIVEN SomeConfig.buildResolvers()
  THEN JavaZonedDateTimeResolver is present in the resolver chain after JavaDurationResolver
• GIVEN JavaZonedDateTimeResolver.canResolve(type)
  WHEN type is String, Int, or java.time.Instant
  THEN it returns false
