docs: 📚 fix conflicting information

[alexrusselldev]

Hi,

I use devmoji and husky frequently, so I spend a little time around that section of your readme.

I noticed that the section that specifies whether to use the commit-msg hook or the prepare-commit-msg hook was in conflict with the section below.

It tells the user to use prepare-commit-msg if they are NOT using the --lint flag, but then immediately shows a code snippet using the --lint flag in a prepare-commit-msg hook.

I've fixed it to show a commit-msg hook, hope this is good!
