Example contract deployment in the documentation does not work, here's the fix

[mathstream]

• Version: 5.30.0
• Python: 3.9.10
• OS: OSX 12.0

What was wrong?

I copy / pasted the example on https://web3py.readthedocs.io/en/stable/examples.html#deploying-new-contracts
(Exactly the steps under Contract Deployment Example)

The Solidity compiler gets a return code 0 and prints "solcx.exceptions.SolcError: An error occurred during execution"
and then a list of command line options.

Now, if I change change the line:
return compile_source(source)
to:
return compile_source(source, output_values=['abi', 'bin'])

then it will compile and run OK.

Found this kinda by accident, I was trying to connect and deploy on Polygon Edge (no success so far) and started pulling things apart to examine each step.

Can I work on this? I just have to change that particular line in the docs right?
