Add per-file owners for remote color resources.

The remote color resources (under `remote_color_resources_res`) were
authored and checked in three years ago by pbdr@, and these resource
files are well isolated from other frameworks resources. It will make
sense to add Pierre as an owner.

Bug: 344870230
Test: Not required. Add owner only.
