chore: fix JavaScript lint errors (issue #11685)

[mvanhorn]

Summary

Resolves #11685.

The stdlib/no-new-array rule flagged two occurrences of new Array( 5 ) in lib/node_modules/@stdlib/math/strided/special/sin-by/test/test.ndarray.js (lines 76 and 84). Both were constructing a 5-element sparse array to drive the accessor's v === void 0 guard.

I replaced each with a 5-element array literal of void 0 values:

x = [ void 0, void 0, void 0, void 0, void 0 ];

The accessor short-circuits on v === void 0, so whether a slot is absent (sparse) or explicitly undefined (dense) is indistinguishable to sinBy. The test's expected outputs remain identical and the assertions still pass.

Changes

• lib/node_modules/@stdlib/math/strided/special/sin-by/test/test.ndarray.js: swap two new Array( 5 ) calls for array literals.
