Add 'version' to manifest

[l3nticular]

Deprecation warning from HA:
-No 'version' key in the manifest file for custom integration 'ge_kitchen'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'ge_kitchen'

I have added a pull request with addition of version to the manifest.json file here:
#10

I am running HA Core 2021.6.2 and the GE Kitchen integration loads properly with this change. You can edit the manifest.json file yourself, here are the specifics:

FYI to anyone looking here, the https://github.com/simbaja/ha_components fork is being actively updated and also supports HACS. If you are running this custom component, I suggest you switch to the components in the fork above.
