Documentation: Add info about the -y cmd line option

[tupakapoor]

I saw it was used in some examples, however I couldn't find what it did described anywhere in the docs, I had to read the source. I think putting it on the CI/CD page would be great - if the docs are open source somewhere I'll be happy to open a PR for it but I couldn't find them.

Just to elaborate more the -y command line option auto applies the changes so that you do not have to enter y and confirm in the terminal every time which is very useful.

Thank you, I did eventually find that written somewhere. Should be in the docs though 😁

@tupakapoor yea I know that you knew :) I wrote my comment for other people who potentially find this thread in the future because you did not write what the option actually does.
