Resolves #7604

Description

What is the purpose of this pull request?

• This pull request fixes a type assertion issue in the @stdlib/stats/base/cumax TypeScript test file.

Previously, the output type was broadly assumed as NumericArray, but with the new generic behavior, when Float64Array is passed as input (e.g., in parameter y), the return type is also Float64Array.

The test currently expects NumericArray, causing the expect-type check to fail. This PR updates the expected type to match the actual inferred return type.
