fix: remove missing logo reference from Helm chart

The referenced logo file (docs/logo.png) doesn't exist, causing
Artifact Hub to fail with 404 errors when indexing the chart.

Commented out the icon line until a logo is created.

Resolves: "error getting logo image https://raw.githubusercontent.com/
lukaszraczylo/gohoarder/main/docs/logo.png: unexpected status code
received: 404"
