chore(deps): bump org.jetbrains.kotlinx:kotlinx-serialization-json from 1.8.0 to 1.9.0

[dependabot]

Bumps org.jetbrains.kotlinx:kotlinx-serialization-json from 1.8.0 to 1.9.0.

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-serialization-json's releases.

1.9.0

This release updates Kotlin version to 2.2.0, includes several bugfixes and provides serializers for kotlin.time.Instant.

Add kotlin.time.Instant serializers

Instant class was moved from kotlinx-datetime library to Kotlin standard library. As a result, kotlinx-datetime 0.7.0 no longer has serializers for the Instant class. To use the new kotlin.time.Instant class in your @Serializable classes, you can use this 1.9.0 kotlinx-serialization version (Kotlin 2.2 is required). You can choose between the default InstantSerializer, which uses its string representation, or specify InstantComponentSerializer that represents instant as its components. See details in the PR.

Other bugfixes

• Fix resize in JsonPath (#2995)
• Fixed proguard rules for obfuscation to work correctly (#2983)

1.8.1

This release updates Kotlin version to 2.1.20, while also providing several important improvements and bugfixes.

Improvements

• Implemented encoding null in key and value of a map in Protobuf (#2910)
• Make type argument in JsonTransformingSerializer nullable (#2911)
• Use SPDX identifier in POMs (#2936) (thanks to Leon Linhart)
• Add watchosDeviceArm64 to Okio integration module (#2920) (thanks to Daniel Santiago)
• Update kotlinx-io version to 0.6.0 (#2933) (thanks to Piotr Krzemiński)

Bugfixes

• Fix incorrect enum coercion during deserialization from JsonElement (#2962)
• Supply proper equals(), hashCode(), and toString() for SerialDescriptor() wrapper (#2942)
• Do not encode empty packed collections in protobuf (#2907)

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
