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?
It is a best practice to have variable declarations outside of the loop. Additionally, declaring variables inside a loop is slightly less efficient because memory management is then performed with each iteration of the loop.
=== Noncompliant code example
[source,sql]
----
BEGIN
FOR i IN 1..10
LOOP
DECLARE
variableX NUMBER:= 10;
BEGIN
variableX:= variableX+i;
dbms_output.put_line(variableX);
END;
END LOOP;
END;
----
=== Compliant solution
[source,sql]
----
DECLARE
variableX NUMBER:= 0;
BEGIN
FOR i IN 1..10
LOOP
variableX:= variableX+1;
dbms_output.put_line(variableX);
END LOOP;
END;
