Fix Chapter 4: Backwards compatibility

[AsamDiegoSanchez]

Describe the bug
It is currently empty

Expected behavior
When no earlier version of the standard exists, add the following content to this section (see in Editorial Guide: 2.1.7 Backward compatibility):

"This is the first release of this standard published by ASAM.
Therefore, no information about the backward compatibility of this standard has been added to this section."

Added to my branch Complete-linguistic-review :) I will commit my changes soon.

@mettelilienthal when you create the pull request for your linguistic review, please make sure to add all issues that are addressed by that in the PR. Best practice is to use the "fixes" keyword, so in this case "fixes #255". Then this issue will be automatically closed, when the PR is merged.

@mettelilienthal When are you planning to merge your branch "Complete-linguistic-review"? It is now 58 commits behind the main branch.
As you said this will addresses multiple issues and I would like to get an overview, over which issues are still open.

We are planning to merge the branch by the end of this week so the native speaker review can start on Monday. It will deal with the remaing editorial issues that are assigned to us: #272, #260, #255.

[ClemensLinnhoff]

Thanks for the information. What about #128?

[FKlopfer]

We have that on our list but it will not be part of the "Complete-linguistic-review" branch. We plan to finish that next week.
