Incorrect Output settings documentation

[JasonGrace2282]

The docs at Manim's Output Settings are outdated. A couple examples:

When executing the command manim -pql scene.py SquareToCircle it was necessary to specify which Scene class to render.

If you want your animations in .gif format instead, use the -i flag.

Hello! I'd glad to be responsible for improving this outdated document. I would like to confirm with you that you have added an anchor for #some-command-line-flags-in-the-link. Does this mean that this issue is only considering fixing this section?

Does this mean that this issue is only considering fixing this section?

Not necessarily, no. If you find anything wrong in any of the other sections, feel please correct that, too!
