Update working-with-the-npm-registry.md

[zizyan]

Document and sample command update based on my testing/experiment. With npm v9, using the command without "--auth-type=legacy" will result in "Web login not supported" error.

Why:

Closes ISSUE

What's being changed (if available, include any code snippets, screenshots, or gifs):

Added instruction "You will be prompted with username, password entering, and please note to use your personal access token as the password upon prompt."

Updated command from
'''
$ npm login --scope=@owner --registry=https://HOSTNAME/_registry/npm/

Username: USERNAME
Password: TOKEN
Email: PUBLIC-EMAIL-ADDRESS
'''
to
'''
npm login --scope=@owner --registry=https://HOSTNAME/_registry/npm/ --auth-type=legacy
'''
