Configuration setting to disable upload prompt

It would be nice if there were a config setting that would disable the following prompt:

```
The command `terminalizer share`can be used anytime to share recordings!
? Would you like to share your recording on terminalizer.com? (Y/n)
```

So that I do not accidentally upload recordings while doing things at work.

Start at the terminalizer share command and inspect how configuration is loaded and how this upload prompt is triggered. Determine where a setting to suppress the prompt belongs, then verify that recordings are not uploaded when it is disabled and that the existing sharing behavior remains unchanged.
