[BUG] - Graph is not working with Grafana 8 and custom icons.

[MariusBrill]

Please provide as much and as detailed information as possible as it will make it easier for us to reproduce and fix the bug!

Describe the bug
As soon as one adds custom icons to the panel, the panel is not signed anymore and Grafana prohibits the panel from being used. This is only applies to Grafana version >= 8.0

To Reproduce
Install the panel and add an icon.

Expected behavior
The panel should remain signed as soon as an icon is added.

Your Setup:

• Grafana-Version: 8.0

@MariusBrill Since I did not really care whether it is signed or not, I did the following to get the panel loaded again:

1. In the grafana config ini, add the panel to "allow_loading_unsigned_plugins"
   allow_loading_unsigned_plugins = novatec-sdg-panel
2. Delete the Manifest file from the plugin directory.
3. Restart Grafana

It will now just throw a warning about plugin bein unsigned.
