Evaluate database(Cosmos, Azure SQL etc) security of all templates

[TWolverson]

I would like to mention in this context that https://github.com/Azure-Samples/todo-csharp-sql effectively disables the SQL firewall by adding an allow-all rule, which is not mentioned anywhere in the readme. Given that this is going to be taken as a reference solution I'd argue this is effectively putting a bomb in code that people will trust is aligned to best practices which it very much is not.

Also consider adding how the password generation works in the security section. https://github.com/Azure/azure-dev/issues/994 has the source code. From what I'm reading, azd calls this command internally, always expects a kv name and key, looks up the secret using the key provided from kv, if it exists, returns it, else generates a new one and returns that

Not a must-fix for GA. Moving to Germanium.

Since Bicep related efforts i.e, moving bicep modules(azure-dev -> awesome-azd), following best practices, moving into bicep registry will be handled in Germanium.
