chore(chart-deps): update oauth2-proxy to version 10.0.0

[merll]

📌 Summary

This PR upgrades the OAuth2-Proxy Helm chart. The application itself has not been updated. However, the values structure already had mismatches before this upgrade, and the Redis configuration is changing with this release.

This required smaller changes in the values migration framework, as it was otherwise not possible to relocate one value out of an otherwise obsolete object and delete it.

Additionally network policies have been added for Redis and the Redis HA setup have been improved.

Pull request overview

This PR upgrades the OAuth2-Proxy Helm chart from version 8.5.1 to 10.0.0, addressing breaking changes in the Redis subchart dependency structure and improving the Redis HA configuration. The upgrade includes enhanced network policies for Redis and refinements to the values migration framework to handle complex value relocations.

Changes:

• Updated OAuth2-Proxy chart dependency to use redis-ha path instead of aliased redis configuration
• Enhanced values migration framework to properly handle relocations before deletions
• Added network policies for Redis and improved Redis HA setup with HAProxy configuration
