Context

Setting a custom logo for the Coder login screen requires manual configuration, with an existing API endpoint /api/v2/appearance available for this. However, there is no support for setting the logo via Helm chart values or environment variables.

Suggestion

Extending support for configuring the custom logo through Helm chart values or environment variables would be beneficial, simplifying deployment and automating the process. This would make it easier for administrators to set and manage the logo during deployment rather than relying solely on the API or manual methods.
