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

== Why is this an issue?
Method references are specialized lambda expressions for methods that already have a name. They take the form of ``++objectReference::methodName++`` or ``++ClassName::methodName++``. When a lambda does nothing but call an existing method, it can be much clearer to use a method reference instead.
=== Noncompliant code example
[source,java]
----
Set roster = transferElements(rosterSource,
() -> { return new HashSet<>(); } // Noncompliant
);
----
=== Compliant solution
[source,java]
----
Set roster = transferElements(rosterSource, HashSet::new);
