[CODEOWNERS] Fix linter errors (Azure#46844)

* [CODEOWNERS] Fix linter errors

The focus of these changes is to remove an account that is no longer associated with Azure SDK development and failing linter checks.   Because there is no other contact for this area, PR reviews have been redirected to the wider team.

* Update CODEOWNERS
