Code Review

This pull request updates the CODEOWNERS file to reassign ownership for three Android packages: google_sign_in_android, quick_actions_android, and video_player_android. The owner for these packages is changed from @ash2moon to @reidbaker. The changes are consistent with the file's existing structure and formatting, including alphabetical sorting of packages and alignment of owner names. The update appears to be a straightforward administrative change as part of code ownership rebalancing, and I found no issues with the changes.
