How to get PRs approved and merged?

I’ve been following this: feat: support policy/v1 on injector-psp for 1.21+ by ellisio · Pull Request #746 · hashicorp/vault-helm · GitHub PR for a while as there are warnings thrown in K8s clusters between 1.21 and 1.25 due to the pending deprecation and removal:

policy/v1beta1 PodSecurityPolicy is deprecated in v1.21+, unavailable in v1.25+

My question is what is missing or required to get this approved and into a release?

I’d like to look for additional opportunities to contribute myself and wanted to ensure any contributes are able to be approved once they meet the requirements.
