Is your feature request related to a problem? Please describe.
Using Node's request API prevents running this SDK in other runtimes like Cloudflare Workers

Describe the solution you'd like
Generate the SDK with typescript-fetch

Describe alternatives you've considered
Generating the client SDK directly from Paystack OpenAPI spec for my own use but making this SDK runtime-agnostic is more future-proof and beneficial to the broader community
