List Users

We need a users command that lists all the users and indicates which one is currently logged in.

Assignment

Add a GetUsers query that returns all the users from the database. Generate the Go code with sqlc generate. Use the :many tag in the comment.
Add a new command called users that calls GetUsers and prints all the users to the console.

Print them in this format:

* lane
* allan (current)
* hunter

Ensure that the (current) follows the currently logged-in user.

Run and submit the CLI tests.
