Update the README

[caarmen]

• Update some of the referenced class names
• Remove the /users path from the local server url
• Update the reference to the sql file for the table creation
• Add an example curl command to create a user (otherwise the example to fetch a user won't return any user). Update the example which fetches a user, to fetch the one just created
• Fix a spelling error

With the current code, the endpoints are at the root /, not /users.

If it's desired to have them at /users, I think something like the following would be needed:

(though probably with a constant somewhere, instead of the string literal repeated).

Maybe there's a way to configure this in one place though 🤔
