chore: fix JavaScript lint errors in chi2gof benchmark (issue #13114)

[NotFoundOvO]

replaced all new Array() constructor calls in the chi2gof benchmark with array literals + push, as the stdlib/no-new-array rule requires.

note: this only fixes the chi2gof benchmark portion of the lint errors. the read-file-list doctest issue appears to be a runtime behavior change that needs deeper investigation.

resolves #13114 (partially)
