* Update readme "and_raise" with error params

I would like to update the documentation for raising errors with required parameters. I have run into an issue multiple times where I've tried to raise an error class which requires args for instantiation like
```
expect(double).to receive(:msg).and_raise(ErrorRequiringArgs)
```
without realising the issue. Ruby gives an error message about "wrong number of arguments", which has repeatedly led me (personally) down troubleshooting other issues.
