Missing maintainers on incubator/sentry-kubernetes helm chart

[hairmare]

I'm trying to expose the LOG_LEVEL env var introduced in 108ae63 in the incubator/sentry-kubernetes helm chart with my PR helm/charts#12060.

The PR seems to fail CI due to the fact that there are no maintainers configured for the chart. I'd be happy to help out maintaining the chart but my track record in the sentry community is nonexistent. If you let me know who to add I'd be happy to prepare a PR that fixes the failing CI due to lack of configured maintainers on the chart.

I'm raising this here since I'm assuming the issue won't surface by just creating an issue on the helm charts repo.

Also, please note that with helm v3, there is a deprecation timeline, so it would be nice to know that whether this chart will be maintained...
