[RFC]: improve type declarations for `@stdlib/utils/async/if-then`

[kgryte]

Description

This RFC proposes improving the TypeScript type declarations for @stdlib/utils/async/if-then. Currently, considerable type information is lost when using this function.

Ideally, we'd improve declarations for x, y, and the done callback.

Thanks for volunteering to work on this, @itsspriyansh. Please feel free to submit a PR improving the declarations.

@iItachiUchiha As you are already assigned an issue, it would be best if you first submit a PR for that issue (and have it merged) before moving onto resolving others.

Actually, @itsspriyansh I see that you have also already been assigned an issue. Please work on #1323 before working on any others. Thanks!

Hey @kgryte, I went through the existing type definition for this function and was able to identify the shortcomings. I feel the type definitions can be improved by incorporating generics. I would like to work on this, could you kindly assign it to me?
