Improve README

The following command fails and the error message suggests removing the .jl extension.

julia> Pkg.add("QiskitOpt.jl")

I'm not familiar with the Julia ecosystem, does it download this package from juliapackages.com? If so, it looks like the last update was a year ago so this command is probably installing an old version. If users should install from source, it wasn't clear to me as a non-Julia user.

I also noticed a small typo (IBQM).

export IBQM_API_TOKEN=YOUR_TOKEN_HERE

Hi @frankharkins !

You are correct. The ".jl" and IBQM are typos. Thank you for pointing it out! I'll fix it right away.

The package is downloaded from JuliaRegistries

https://github.com/JuliaRegistries/General/tree/master/Q/QiskitOpt

There you can see that it is updated.

QiskitOpt is aimed for Julia's mathematical programming framework JuMP users.

So if you would like to use it, you first need to

1. download Julia https://julialang.org/downloads/
2. open Julia in your terminal and add JuMP and QiskitOpt with

using Pkg
Pkg.add("JuMP")
Pkg.add("QiskitOpt")

And then you should be able to run the code in the README.md file.
