This PR solves issue #13407

There is an issue with the readme.md where if you check the Code-of-conduct tab in the readme and click on the can be found online link, it redirects to a 422: Unprocessable Entity. Fixed this by changing the link to the actual code-of-conduct link.

Thanks for the fix!

While this does resolve the issue, I am not sure since when the link is broken. We might want to reach out to https://github.com/rust-lang/www.rust-lang.org/ to have a redirection.

I see, I thought the Code of Conduct link was moved to a different link and it was not updated in the readme.
Will we need to fix it in the www.rust-lang.org repo?

The old link was used in pre 2018 website: https://prev.rust-lang.org/conduct.html. And here are redirection rules. I am not sure why it didn't work. Maybe something wrong when upgrading Rocket to v0.5? We can clone the repo and debug there.

Since this link is used in a couple of different repository (rust-lang/rust, rust-lang/rust-clippy, …), I lean towards fixing in the redirection. If we cannot find the root cause, then contact Manishearth as they are the only member on the website team.

Okay then, I will try to fix this redirection issue and give an update here

Close as fixed in rust-lang/www.rust-lang.org#1924. Regardless, thanks for your help :)
