Remove reference to analyzerChecksInternal (#530)
Remove reference to analyzerChecksInternal (#530)

This is a no-op: in older versoins of Closure copmiler this diagnostic
group is a strict subset of analyzerChecks. As of
https://github.com/google/closure-compiler/commit/09e5fdf5af2a86f9ca92462b61c062224766646e,
the diagnostic is deprecated and an alias of analyzerChecks.
