Add language to code blocks in spec (#5502)

* Add "scala" language code to pure-Scala code blocks.
* Add "java" language code to Java code block.
* Add "scala" language code to almost-pure-Scala code blocks.

Add "scala" language code to two code blocks whose content was Scala except
for containing ellipses (\ldots).

* Add "scala" language code to non-literal-Scala code blocks.

Add "scala" language code to code blocks that contain Scala but also special
elements, such as identifiers that are italicized or have prime marks (e.g., e′,
e′′), ellipses (\ldots), etc.
