chore(kubernetes): stop specifying the version of io.kubernetes:clien…

…t-java (#5797)

since spring 2.4.13 brings it in (transitively).  The version from spring boot takes
precedence, so the value we specify here is ignored.

Another approach would be to make the version here match what spring boot brings in
(currently 11.0.3), but then future changes could again invalidate what's here.  If some
future version of spring boot stops bringing in io.kubernetes:client-java, builds will
fail with unspecified version, at which point we can restore kubernetesClientVersion.
