Move `type-fest` to development dependencies

[mahnunchik]

I think it is better to move type-fest module to development dependencies.

Motivation: it doesn't required in compiled .js file.

And I don't need typescipt in my application in production:

└─┬ p-memoize@7.1.1
  └─┬ type-fest@3.10.0
    └── typescript@5.0.4

The type is used in production, so that would be a mistake. As for the typescript thing, see: https://github.com/sindresorhus/p-memoize

Ok, got it, typescript is cancer on the body of modern js.
