Resolve accidental breaking change with type inference on array types

The combine* family of functions (both sync and async) broke any codebase that called these functions on arrays of varying lengths when the previous release was shipped:

https://github.com/supermacro/neverthrow/releases/tag/v5.1.0

The following fix was implemented to address this issue and ensure that arrays (not just tuples) work with the combine* family of functions.

#435

Why is this shipped as a MAJOR version change?

Because we are now explicitly depending on TypeScript's variadic tuple types feature, which came out in v4 of TypeScript:
