Use launcher stub template from bazel

This was added in bazelbuild/bazel#12994 (and fixed in bazelbuild/bazel#13790). This has been included in all Bazel releases since 5.0.0, which is the minimum supported Bazel version of rules_kotlin according to https://github.com/bazelbuild/rules_kotlin/blob/master/README.md This prevents having a build-time dependency on access to raw.githubusercontent.com.
