object_store release tarballs are missing LICENSE and notice files

[alamb]

Describe the bug
As reported by @Xuanwo on the 0.11.0 release thread https://lists.apache.org/thread/wxppr3ronhj9h03thltc1gk1ocqxfx4w

However, I noticed that our tarball is missing the LICENSE and NOTICE files. I believe this is something we need to address.

To Reproduce

Download https://dist.apache.org/repos/dist/dev/arrow/apache-arrow-object-store-rs-0.11.0-rc1 and inspect the contents. They are indeed missing LICENSE and NOTICE.
