Add @micahhausler as trusted colaborator

[micahhausler]

I work at AWS, am a member of the Kubernetes and Kubernetes-sigs Orgs, am a member of the K8s Product Security Committee, and am maintainer for the following project and would like to be a maintainer for the chart:

stable/aws-pod-identity-webhook #17099

/cc @plumdog @nckturner

If you want to be added as a maintainer for a specific chart, I think you need to follow https://github.com/helm/charts#owning-and-maintaining-a-chart, rather than https://github.com/helm/charts#trusted-collaborator which I think is about becoming a global owner.
