Pull request overview

This PR deletes the CODEOWNERS file from the repository as it is stated to be out of date. The file previously defined code ownership rules for various packages and components including error analysis, responsible AI widgets, SDK packages, UI libraries, and e2e tests.

Changes:

• Complete removal of the CODEOWNERS file containing 44 lines of code ownership definitions

Comments suppressed due to low confidence (1)

CODEOWNERS:1

• The CONTRIBUTING.md file references the CODEOWNERS file on line 249 with a link to "https://github.com/microsoft/responsible-ai-toolbox/blob/main/CODEOWNERS". After this deletion, that link will return a 404 error. The documentation should be updated to either remove the reference to the CODEOWNERS file or update the text to reflect the new code review process without CODEOWNERS.
