[flyingsilverfin]

Goal

Update the Console documentation to reflect TypeDB Console 3.1.0: no more core/ccloud split, the --script argument and its requirements (eg. terminating queries with a newline), and the transaction command argument order.

Implementation

1. Remove the Core and Cloud differentiation - Console has no distinction now.
2. Document requirements of console scripts, in particular newline termination.
3. Document the order of arguments to open a transaction
4. Update example inputs and outputs
5. Update CLI argument changes
6. Document some of the shortcuts and tricks of Console
