Code of Conduct Link Incorrect

[Rjae]

Link in Code of Conduct is:

[Serilog Code of Conduct](https://github.com/serilog/serilog/blob/dev/CONTRIBUTING.md)

But should be:

[Serilog Code of Conduct](https://github.com/serilog/serilog/blob/dev/CODE_OF_CONDUCT.md)

Thanks for the heads-up, @Rjae 👍

Your PR linked above is targeting dev in your fork, rather than in this repository, so we can't merge it directly. I can make the change here by hand, but if you'd rather set up a PR with the above change, let me know, happy to help.

Sounds good, might as well make the change there. 👍
