Update Kotlin client of version 2.1.* to ktor-* artifacts of the new versions to avoid CVE-2023-45612 and CVE-2023-45613

[dmitry-weirdo]

Is your feature request related to a problem? Please describe 🙏
Currently, the io.ktor:ktor-* artifacts of version 2.2.3 are hurt by the critical CVEs — CVE-2023-45612 and CVE-2023-45613.

Describe the solution you'd like 🤔
No need to wait for the breaking 3.0.0 release. Please add a new release that updates the io.ktor:ktor-* artifacts to the current latest versions (i.e. at least 2.3.5 or better 2.3.6 versions that fix the mentioned CVEs).

Describe alternatives you've considered ✨
Client version 3.0.0 MUST definitely depend on the updated io.ktor:ktor-* artifacts.
