Update Codeowners rule (#36361)

Remove API review rule from the Codeowners file to unblock service team.
Copying's Maor's text before resolving conversation to merge the PR:

> Context:
> 
> - GA package shipping is blocked pending APIView approval
> - As of 2024, _all_ CODEOWNERS (per group) must sign off on a PR to
allow merging
>   - Prior to that, _any_ CODEOWNER group can sign off on a PR
> - While it is helpful for me to review api.md files in smaller diffs
(give a developer 10 lines to review and they'll find 10 problems, give
them 100 lines and they'll say "looks good" 😄 ) , I think with APIView
Copilot improvements and standardization of our client libraries using
codegen we can probably view the APIView changes
> - Speaking of standardization, we're moving more and more towards
codegen first with minimal hand-authored changes, so that's probably
another reason to relax this restriction
> - When a package is first prepped for release we still need to approve
the name which acts as a forcing function to giving the public API a
review as well
