Fix inference command sample in README.md

[jasoncwik]

The inference sample in README.md did not work for me and I noticed there was a missing line continuation in the command line.

Hey Jason, thanks for the contribution!

Similar to step 1, I believe those are intended to be 2 separate commands, not a single one. If you copy and paste them individually, the sample should work. The difference is whether or not you'll stay in the container interactively after the command finishes.

Are you seeing otherwise?

[jasoncwik]

Got it. I guess it wasn't immediately clear to me that you wanted to launch the container and then paste the command inside the container. I had copied and pasted both lines and the 2nd line paste didn't work automatically for some reason. IMO unless you have a reason to keep the user in the container, it's a little cleaner to make it one line, but I'll defer to you.

Oh, I suppose if it's decided to make it one line you could remove the -it too...
