* docs(angular): update 'npm run' to 'npx nx' for affected commands
The tutorial refers to using 'npm run' for the affected commands, which doesn't work if the
workspace is generated using yarn.
To fix that, change it to 'npx nx' so it works in all cases,
like other places in the docs.
* chore(misc): fix formatting
