Chapter 8 "Runtime Scenario" overview in violation of asm-132
For chapter 8 "Runtime Scenario" an overview was added. According to the ASAM Editorial Guide https://internal.pages.asam.net/asam-editorial-guide/editorial-guide-generator/editorialguide-asciidoc/1.0.0/Editorial_guide/02_structure.html#sec-ASM-132 (Section 2.5) no text between section levels should exist. Removing this and adding the name to the index also makes the chapter consistent with the other chapters.
