feat: update dex application on Plural

[pacoguzman]

Summary

Bump dex helm chart to latest version

Test Plan

I wasn't able to test it as per the problem indicated here based on the following error

plural link helm dagster --path ../plural-artifacts/dagster/helm --name dagster
2023/03/18 11:08:15 open /Users/pacoguzman/dev/github/pacoguzman/pluralsh-repo/dagster/manifest.yaml: no such file or directory

Saying that I'm willing to test it throughly when added to the catalog and the manifest.yaml will be avaible. Please let me know if I took wrong assumptions about the issue.

Checklist

• No images hosted from dockerhub
• Are dashboards present to understand the health of the application. There must be at least 1 of these
  • all databases should have dashboards
  • ideally also have at least cpu/mem utilization dashboards for webserver tier of the app
  • you can use plural from-grafana to convert a grafana dashboard found via google to our CRD
• Are scaling runbooks present
  • all databases must have scaling runbooks
  • you can use the charts in pluralsh/module-library to accelerate this
• do you need to add config overlays?
  • inputing secrets
  • configuring autoscaling
• If there’s a web-facing component to the app, we need to support OIDC authentication and setting up private networks if no authentication option is viable
• All major clouds must be supported
  • Azure
  • AWS
  • GCP

Hey Paco, were you interested in using dex? We left it dormant because we couldn't think of an obvious use case but are happy to change our mind on it

As far as the error you, you just didn't dive all the way to the right dagster chart, it would need to be ../plural-artifacts/dagster/helm/dagster (needs to be the dagster chart w/in the helm folder)
