Using image vs fly.toml for launching app

[SimonLab]

On the create an app section we have the following command:

flyctl launch --name gogs-server --image gogs/gogs --org dwyl

This will create a new Fly app with the gogs image, (I guess from https://hub.docker.com/r/gogs/gogs).
However the fly.tomlalso contains in the build section the gogs image:

gogs-server/fly.toml

Lines 12 to 13 in 5e434c7

	[build]
	image = "gogs/gogs"

So could we instead of using the --image gogs/gogs flag, just run

flyctl launch --name gogs-server --org dwyl

We could also not pass the --org flag and let the command line ask later on the launch step I think.

@SimonLab yeah, I was just building it from first principals as if the fly.toml file didn't exist. ✍️
But yeah, we could update the docs to the command you suggest now that the file is there. 💭
