Inline adoc when include has no additional value (#1940)
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?
There is no need to declare a type parameter when naming a type constraint is not required. Using wildcards makes it easier to read.
=== Noncompliant code example
[source,java]
----
<T extends MyClass> void foo(List<T> list) { // Noncompliant, T is used only once
for (MyClass myObj : list) {
doSomething(myObj);
}
}
----
=== Compliant solution
[source,java]
----
void foo(List<? extends MyClass> list) {
for (MyClass myObj : list) {
doSomething(myObj);
}
}
