Contributing docs recommend running bash on container with user that doesn't have npm installed

Is your feature request related to a problem? Please describe.
The contributing documentation states in it's step by step setup guide that you should run bash on the docker container using the command docker compose exec -u www-data nextcloud bash. This command runs bash using the user www-data, that doesn't have nvm, npm or Node installed, since it is installed locally on the root user.

Describe the solution you'd like
Remove the -u www-data argument from the command on the contributing documentation.

Describe alternatives you've considered
Install nvm and Node on the www-data user, but it would need to be done on the nextcloud-docker-development repository.

Both is good.

Now we have a good repository to implement this documentation:
