Docker : Fix Dockerfile inspired by Kubo official Dockerfile

[FournyP]

Hi,

I've done this little change in the Dockerfile on my side for a personal project.

The build is clearly inspired by the official Kubo Dockerfile. Imo it's make more sense than the older one.

It also bring the flexibility of the Kubo Dockerfile.

And the jq depency is downloaded in another FROM for paralleling purpose (as Kubo Dockerfile do in the utilities FROM).

Errors on the screen are because I didn't map the ports

Have a nice day
