Update CODE_OF_CONDUCT.md

[prithvi1307]

Description

The PR is raised as the code of conduct for k0s wasn't defined and was redirecting to the CNCF coc. It is updated with all the guidelines and this Code of Conduct is adapted from the Contributor Covenant version 2.1, available at https://www.contributor-covenant.org/version/2/1/code_of_conduct.html.

Community Impact Guidelines were inspired by Mozilla's code of conduct enforcement ladder.

Can you maybe add a quick gist of your changes (why and what) to the commit message and the PR description?

Do we want to include the Code of Conduct also in the k0s docs?

[prithvi1307]

Hey @twz123 I have updated the gist. We can include this Code of conduct for the docs too. But not needed for now.

@prithvi1307 The linter has some complaints. Would you mind addressing them?
