Move Kotlin serialization gradle plugin into libs.versions.toml (#6254)

A previous change,
#6186, added the
Kotlin serialization plugin to every single Gradle module; however, only
one module actually used it. Moreover, it is becoming more conventional
to define dependency versions in `gradle/libs.versions.toml`. This PR
removes the global dependency on the Kotlin serialization plugin and,
instead, moves the version into `gradle/libs.versions.toml`, and also
modifies the dependency on the Kotlin JSON serialization library to use
`gradle/libs.versions.toml`. This will make sure that every module uses
the same version, which will become important once Data Connect, which
also uses these libraries, is merged into main.
