What problem is this PR intended to solve?
Add test coverage for HTML parsing of processing instructions, and update the packaged nekohtml library used for the JRuby implementation.
(backport to v1.13.x)
Have you included adequate test coverage?
Yes, additional coverage provided.
Does this change affect the behavior of either the C or the Java implementations?
The Java implementation is still different from the C implementation for HTML4, but test coverage describes those differences.
