Describe the bug

Steps to reproduce

1. Set up a simple Bazel project (see https://github.com/sourcegraph/jetbrains/issues/1719 for instructions)
2. Open the BUILD file.
3. Select one of the target definitions and invoke "Document code".
4. The generated comment will be delimited by /* */ (like in Java). This is incorrect syntak for Starlark.

Expected behavior

In Starlark, comments are marked by a # at the beginning of the line (like in Python).
