docs(README.md): update husky hook file creation

[jpbnetley]

updated the "commit-msg" hook creation. Fixed ENOENT: no such file or directory, open error on pre-commit

Description

Following the docs mentioned here I noticed 2 things.

1. The file creation portion doesn't work for me (using macOS Or WSL Ubuntu on Windows)
2. When I create the file manually - the commit-msg hooks gives the error ENOENT: no such file or directory, open error on pre-commit`

Motivation and Context

1. updated the file creation to use echo and the output redirection operator.
2. noticed the error ENOENT: no such file or directory, open error on pre-commitis to do with the sting interpellation. changed the string from"${1}"to${1}` (removed the quotes)

Usage examples

In the root of the project directory, can now just run

echo '
#!/bin/sh
. "\$(dirname "\$0")/_/husky.sh"

npx --no -- commitlint --edit ${1}
' > .husky/commit-msg

How Has This Been Tested?

I created a new folder structure on my desktop .husky and ran the command to see if the file gets created with the correct content inside of the file.
