Remove warning in task :kotlin:compileKotlin (#4368)

Motivation: Noticed some warnings while building the project: `> Task :kotlin:compileKotlin w: Argument -Xopt-in is deprecated. Please use -opt-in instead w: /Users/wjdalstn/Documents/GitHub/armeria/kotlin/src/main/kotlin/com/linecorp/armeria/client/kotlin/CoroutineRestClient.kt: (33, 12): Type parameter 'T' has nullable upper bounds while non-nullable version is expected. This warning will become an error soon. See https://youtrack.jetbrains.com/issue/KT-36770 for details w: /Users/wjdalstn/Documents/GitHub/armeria/kotlin/src/main/kotlin/com/linecorp/armeria/client/kotlin/CoroutineRestClient.kt: (33, 20): Type parameter 'T' has nullable upper bounds while non-nullable version is expected.

This warning will become an error soon. See https://youtrack.jetbrains.com/issue/KT-36770 for details` Perhaps something related to the definitly non nullable types feature since kotlin 1.6.20 Modifications: - Providing upper bound Any removes the warning Result: no warnings!
