Bazel 6 example workspace

[hcnguyen5]

My team is currently using a Makefile with j2objc but we want to transition our build system to Bazel 6 and the j2objc example here hasn't changed in 5 years and I haven't been able to find more recent examples out on the Internet.

In particular, how to use Bazel's built in j2objc_library rule with third-party jars like androidx.annotations.

Unfortunately all of my company's code is private so I can't share my bazel files.

I'm aware that Google uses Bazel/Blaze internally so I'm wondering if there's another Google open source project that is using j2objc that I can glean some insights from?
