Fix some documentation typos & grammar

[trinitronx]

Fixing some documentation typos + grammar:

• Fix Chef Effortless doc typo: "help with you with" => "help you with"
  • "Obvious fix" DCO rule (but GPG signed anyway, as I usually do...)
• Ran paragraph through Grammarly:
  • Simplified repeated "better manage"
  • Adjusted comma usage
  • Removed 'to' articles
  • Feel free to revert this commit if you don't like what it did.

Looks like the CI failure is from GitHub's recent disabling of git:// protocol.

fatal: remote error:
      The unauthenticated git protocol on port 9418 is no longer supported.
    Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information

Seems reproducible locally with pre-commit
