Update bazel_deps and fix building for some examples

[cheister]

I went through and updated most of the bazel_deps and also made sure the examples all build.

Updating stardoc past 0.7.1 or rules_java past 7.12.4 results in the error:

in deps attribute of starlark_doc_extract rule //docs:defs.extract: missing bzl_library targets for Starlark module(s) @rules_java//java/private:proto_support.bzl. Since this rule was created by the macro 'stardoc', the error might have been caused by the macro implementation

during build
