Fix two issues with the Java syntax highlighter lexer

Browse source 
Summary:
Ref T13202. See PHI886. Two minor issues here:

  - I translated the double quoted string regexp incorrectly; we don't need to include backslash ("\") in the last character class. With it included, we failed to match `"\n"`. We now match `"\n"` as a complete string literal correctly.
  - The class for "t" should be "kt", i.e. "Keyword.Type". For now, this is pretty informal; some day it will presumably be better formalized.

Test Plan:
Got proper highlighting output for this snippet:
