MINOR: Fix Javadocs for SourceTaskContext::transactionContext and SinkTaskContext::errantRecordReporter to use NoSuchMethodError instead of NoSuchMethodException

[yashmayya]

• NoSuchMethodError is thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
• NoSuchMethodException is thrown when trying to reflectively access a method that does not exist.
• Both the SourceTaskContext::transactionContext and SinkTaskContext::errantRecordReporter methods use NoSuchMethodError in the example code block (which is the correct Throwable to use in this situation) but incorrectly specify NoSuchMethodException in their Javadocs.

Hi @gharris1727, I noticed this small discrepancy after our related discussion here. Could you please take a look whenever you get a chance?

Thanks for the fix! I like that the code sample is correct but the Javadoc is wrong :)
It also looks like there's no other similar mistakes.

LGTM!
