docs(Configuration): adding visual content and improve structure for brevity

[DevTKSS]

Visual Content to simplify understanding possibilities (skip and list of skips can be tricky)
added information about help argument is available
Seperated CI topic to own area

Done:

• Will check if toc.yml needs future adjustments
• Check added files to be linked properly
• Enhanced Readme.md file so it can also be used as Intro

TODO:

• Build has to show if the link to UnoCheck.Intro is successfull this way

Help needed:

• Structure inside of Tabs should be unified similar to api docs with syntax, explaination incl. sample and to be checked synonym arguments, but this could also be done in syntax area before.

@agneszitte FYI: all checks passed here :)

@Takoooooo added the local images I meant already now, maybe you want to take a look and replace if yours is localized correctly so i could link them then later on

Let's keep using english for the screenshots

@jeromelaban okay, then I will need someone to help for the screenshots, as my system is only german and until now I did not found an option to tell dotnet cli I want en-US loc output.

@DevTKSS you can simply "set DOTNET_CLI_UI_LANGUAGE=en" if you are on Windows

• checked the INCLUDE links
• squashed for brevity to keep only the essential ones, squashing chore commits e.g. formatting
• Added cases for tfm which seem to result in [!TARGET FLAG BUG!][WinSdk][Desktop][Banner][VS2022] "Found problems banner" while the --target flag gives green light does not run the minimum Checks! #404 as the desktop or winsdk flags are not known

To check: the tfm flag should normally not be equal to the target flag:

--target should stand for the current checked targets like desktop, windows, winsdk ios or android
--tfm should stand for the net version like net9.0 or net10.0 in the future or major-prerelease case

Seems like this is indeed failing just because of issue #417 While I did not even realize the CI would fail on this PR because of the version 😅
I am curious how that worked out before. 🤔
