Add quick start example

[ifavo]

This PR aims to simplify the start for impatient developers on the app template:

• Adds a QuickStart.md with reduced information and a single snippet to get started
• Documents the links that will be available
• Defaults the log dir, to use less config variables

Like the idea of the quickstart! But

OPENAI_API_KEY="sk-proj-.." would configure the backend with a wrong API key

Users might mistake the steps as a copy and paste and everything will work.

Possible solution could be adding the "Result" section of the Quickstart below the Readme here:

Adding Request Change

Possible solution could be adding the "Result" section of the Quickstart below the Readme here:

👋 not sure what you mean by that. Would this be adding the link table to the first section?

I agree with the potential copy & paste misunderstanding. It is stated at the top as required variable.

I went back with my original frustration about the required amount of ENV and found that envalid is used to verify PORT and NODE_ENV only.
I've modified it slightly to verify all the ENV and also use the verified ENV. In the process adjusted, it now also sets some default values and has an OpenAPI-Key verifier, that informs the user where to obtain one.

What do you think about the change?

Nice catch! Could you have a reference to the Quickstart.md in the Readme.md too?

I did add a link to the README, hope its what you expect. Feel free to adjust the way you like to see it!
