added the a scripts help generate secret key

[martcpp]

This pull request involves changes to improve the configuration and security of a Django project. The most significant changes include the introduction of a script to generate a secret key, changes to the ALLOWED_HOSTS and SECRET_KEY settings in hello_world/settings.py, and updates to the README.md and .env.example files.

Security improvements:

• secretgen.py: A new Python script was added to generate a random secret key for Django projects. This script uses Django's get_random_secret_key function to generate the key and instructs the user to replace the secret key in their .env file with the generated key.

Documentation updates:

• README.md: Instructions were added on how to generate a secret key for a Django project using the new secretgen.py script.

Thanks for digging into this! One thought and question ⚡

What's the motivation for moving this into here, instead of keeping it in .env?

[martcpp]

it is easy to access rather than keeping it in .env file and other will know it part of the setting as we don't push .env to GitHub @joshaber

What do you think about generating the secret as part of the postCreateCommand, so that devs don't have to manually do anything? The script is definitely an improvement, but ideally folks wouldn't have to know/care about generating the secret.
