docs: add missing double hyphen to npm husky command in setup guide

[Marukome0743]

Description

Documentation:

• Add missing -- flag to the npx commitlint command in the husky commit-msg hook example in the local-setup guide

Usage examples

npm install --save-dev husky

npx husky install

# Add commit message linting to commit-msg hook
echo "npx --no -- commitlint --edit \$1" > .husky/commit-msg
# Windows users should use ` to escape dollar signs
echo "npx --no -- commitlint --edit `$1" > .husky/commit-msg

As an alternative you can create a script inside package.json

npm pkg set scripts.commitlint="commitlint --edit"
echo "npm run commitlint \${1}" > .husky/commit-msg

How Has This Been Tested?

I have tested on my local PC.
