Add Anna Jung as reviewer

[kimwnasptd]

Following up with another way overdue PR, for adding @annajung as a reviewer in both repo wide and in /contrib sub-directory.

Anna has made huge contributions to the manifests repo throughout the last 2 years. Some highlights:

1. Helped shape and review the release handbook, that contained the release process for manifests First iteration of the Release Hanbook #1907
2. Worked on the testing of manifests and how to setup an E2E infra (in-progress [doc]) Alternative solution to removal of test on optional-test-infra testing#1006 Update kubeflow/katib manifests from v0.14.0 #2273
3. Has been a release manager for KF 1.6 and run the whole lifecycle of updating the manifests https://github.com/kubeflow/community/blob/master/releases/release-1.6/release-team.md
4. Has lead the effort of cleaning up the /contrib repo Tracking for /contrib components evaluation and clean up #2311

The above contributions touch all the pillars of the manifests repo:

1. Experience with the release process
2. Overview of the testing infra
3. Work/Reviewing the current addons we have

The above list, plus contributions on the common components owned by manifests (Istio, Knative, Cert Manager etc), is what I consider the main areas for promoting someone as an approver to the repo. And of course having a track record of being able to efficiently communicate and lead efforts in this areas.

So with the above I propose Anna to be a reviewer for both /contrib and for the whole repo

/cc @kubeflow/wg-manifests-leads

NOTE: I'm removing the current reviewers, since they are already in the approvers list

I also want to say that we'll need to do a better job at defining the requirements for someone to be a subproject owner (approver in root OWNERS file of a repo). I think this is an area that is very hazy. Maybe this could be done in kubeflow/community#591

[annajung]

Thanks @kimwnasptd! I hope other community members will also support this decision. Look forward to continuing the work on improving the overall integration and testing of the kubeflow and the Kubeflow release!

Just want to give my +1 on this, Anna has been a great contributor to the project.

Really happy that we more people are getting involved with this WG! @kimwnasptd I agree with your rationale, and @annajung definitely fits these requirements to be a reviewer.
