rPHUdb3667a62f66: Add an upstream JSON fragment lexer

Summary

Ref T9566. This seems to be >100x faster than an older version of pygmentize for JSON inputs with a single long line. See discussion in D14273.

Test Plan

Verified runtime improvement by comparing scripts/highlight.php on the one-line.json test case from D14273 with the new lexer enabled and commented out. Saw >10x local improvement. My local base runtime is also >10x better than the runtime from D14273. My laptop might be a little faster than whatever that hardware was, but this is probably mostly pygmentize improvements in my most recent version.
Added a test case.
Used the highlighter to produce reasonable-looking results:

Actually, just fix lint by excluding __tests__/data/, which seems reasonable for all similar cases.

Just exclude every /__tests__/data/ directory from all linters.

(I'm going to hold this until the release cut tomorrow morning since some issues might crop up once it gets a little more use and it sounds like "upgrade pygments" fixed most of this anyway.)
