Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
In PHP, keywords and constants are case-insensitive, meaning they can be written in either lower case or upper case without affecting their functionality.
|
|
This allows for more flexibility and ease of use when writing code.
|
|
|
|
However, it is generally recommended to follow a consistent casing convention for readability and maintainability purposes.
|
|
Relevant constants are `true`, `false` and `null`.
