@opensearch-project/admin Please help update the maintainers. Thx!

[gaiksaya]

Added @ykmr1224 as the new maintainer.

The codeowner file is still invalid due to below errors.

Please take action to either add them back or move the maintainers to emeritus section if they do not wish to continue.

Thanks!

you can move me to emeritus section, i haven't done much in this repo

Thanks @joshuali925 for the status update.

Also regarding this PR and codeowner file invalid issues.

We still need @mengweieric to confirm if he will continue be the maintainer, or move to emeritus.

We will then need a PR to fix codeowner file, and I will also fix the collaborator section before certain settings take effects.

Next time, please make sure to open the PR in draft mode, so admin can verify and update collaborator before the merge to avoid these kinds of issues happening again.

Thanks.
