This commit will update the okhttp version to 4.12.0 in pom.xml. This update is done to fix the Github issue #503. (#505)

* This commit will update the okhttp version to 4.12.0 in pom.xml. okhttp-4.12.0 uses okio-3.6.0. This update is done to fix the Github issue #503.

* This commit upgrades Kotlin from 1.7.20 to 1.9.0 in pom.xml. This is done to address the CI workflow errors because okhttp-4.12.0 is pulling okio-3.6.0 which is compiled using Kotlin 1.9.0 but the our SDK's pom.xml is expecting Kotlin metadata compiled with Kotlin 1.7.20.
