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:

• [x] Will check if toc.yml needs future adjustments
• [x] Check added files to be linked properly
• [x] 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.
