[ThiagoCruzBr]

Alternative command useful for automation.

This pull request contains a documentation issue where a hardcoded weak password ('Password123!') is included in the Docker setup instructions, which could potentially lead to security risks if users directly copy and paste the example command without changing the password.

Hardcoded Weak Password in Documentation

Description

The documentation file readme-docs/DOCKER.md contains an example command for changing the admin password that includes a hardcoded, weak password ('Password123!'). This command is presented as an alternative for automation, implying it's intended for users setting up their instances. Users are highly likely to copy and paste this command, which could lead to production systems having a known, easily guessable administrator password, thereby creating a significant security vulnerability.

	docker compose exec -it uwsgi ./manage.py changepassword admin
	```
	Alternatively, you can run the command below to change the admin password in a single command. Useful for automation.
	```zsh
	docker compose exec uwsgi ./manage.py shell -c 'from django.contrib.auth.models import User; u = User.objects.get(username="admin"); u.set_password("Password123!"); u.save()'
	```
	# Logging
	For docker compose release mode the log level is INFO. In the other modes the log level is DEBUG. Logging is configured in `settings.dist.py` and can be tuned using a `local_settings.py`, see [template for local_settings.py](../dojo/settings/template-local_settings)). For example the deduplication logger can be set to DEBUG in a local_settings.py file:
