Pull request overview

Updates the groovy-yaml module documentation and tests to clarify how temporal values are represented in untyped vs typed parsing, and improves typed Jackson databinding support for java.time.* types.

Changes:

• Document that untyped YamlSlurper.parse/parseText returns YAML date/time scalars as String, and explain why.
• Add spec tests covering typed round-trip of OffsetDateTime/LocalDate/LocalTime and pin untyped string behavior.
• Configure the Jackson ObjectMapper used by typed parsing and YamlBuilder.toYaml to register JavaTimeModule and adjust date/time features.

File	Description
subprojects/groovy-yaml/src/spec/test/groovy/yaml/YamlParserTest.groovy	Adds temporal round-trip tests for typed parsing and asserts untyped parsing returns strings for temporal-looking scalars.
subprojects/groovy-yaml/src/spec/doc/yaml-userguide.adoc	Updates the type mapping table and adds notes/section describing untyped vs typed temporal handling and examples.
subprojects/groovy-yaml/src/main/java/groovy/yaml/YamlSlurper.java	Introduces a shared Jackson ObjectMapper factory registering JavaTimeModule and disabling specific date/time features for typed parsing.
subprojects/groovy-yaml/src/main/java/groovy/yaml/YamlBuilder.java	Reuses YamlSlurper.mapper(...) so typed YAML writing gains the same java.time configuration.
subprojects/groovy-yaml/build.gradle	Adds jackson-datatype-jsr310 to support java.time serialization/deserialization.
