Add support for proxies to scripts

Update jcabi-aether dependency from 0.10.1 to 1.0-SNAPSHOT. In order to
do that, add https://oss.sonatype.org/content/repositories/snapshots to
the repositories in tools/kotlin-script-util/build.gradle.kts

Script dependencies are resolved using jcabi-aether. Unfortunately "stable"
release (0.10.1) does not support proxies. Therefore, script dependencies
are not pulled behind a proxy. Issue is fixed in SNAPSHOT release of
jcabi-aether.

FIXED: KT-22363
