Allow ghost backup to run with --no-prompt, take authData from command line arguments

[tonydelanuez]

ghost backup --no-prompt wasn't actually taking the arguments from the command line required to properly call the exportTask (authData).

This commit checks for authData {username, password} from the command line and passes through to the necessary task calls.

The test spec setup for these were a bit odd (I've never looked at this codebase before but this was blocking my work), so here are some screenshots? 😅

Note: One of the screenshotted "working" calls fails because localhost in Node 18 automagically favors iPv6. We successfully auth for the backup process with --no-prompt and some auth arguments.

Throw SystemError when not username and password passed but in no-prompt mode:

Without --no-prompt, use AuthData from interactive CLI:

With authdata provided and --no-prompt, successfully auth (don't worry, test password for my local dev instance):

Working on my actual Ghost instance:

tdoot@util-arm:/var/www/decked$ ../../code/Ghost-CLI/bin/ghost backup --no-prompt --username <redacted> --password <redacted>
