Add the "Quick Workflow" page

[hardBSDk]

The Quick Workflow page will add how to do the most common tasks on Godot, mostly using scripts.

Motivation

Separate tutorials in many pages is time consuming for people that want to find things quickly.

For example, I want to find how to use full screen on my games because OS.window_fullscreen = true doesn't work anymore, I still can't find proper documentation.

For migration from 3.x you should read the appropriate page, otherwise you already have the getting started part, which does cover the generals and basics, otherwise the relevant pages should be used IMO, no reason to duplicate things

@AThousandShips The "Quick Workflow" would point to other pages or sections of other pages.

I do see the appeal of a page like this. See also the older issue #3182, which addresses a similar problem in a different way.

There is precedent for pages which are a partly collection of redirects to other pages, such as the FAQ or troubleshooting pages. We could add a page which has only a list of "How do I do X?" questions, and answers which are links to other sections:

How do I quit a game?
See <Handling quit requests>.
How do I raycast?
See <Ray-casting>.
How do I make the game fullscreen?
See <Multiple resolutions>.
...

There are a couple of problems with this:

• At some level, it's just a redundant, verbose version of the sidebar.
• Not every question has a clean example to link to. Some answers do require the full page of context that leads up to the two line code example that solves the problem.
• Some of the examples might be from the class ref, not the manual. That's fine, but it creates a fragile dependency on the contents of the class ref.
• Since the whole page is links, it's all dependencies on other pages which have to be maintained.
