chore: Migrate from CommonJS to ECMAScript Modules (ESM)

[gaganbiswas]

Changes

• Resolved the issue documented in Replace the request package by something else (DEPRECATED) #343 effectively closing it.
• Removed deprecated and unmaintained dependencies, specifically addressing security concerns related to Prototype Pollution and Server-Side Request Forgery vulnerabilities in request and request-promise. Introduced axios as a replacement for improved security.
• Rectified a bug in the package.json scripts. Now, executing the cp-types script correctly creates a types directory inside the dist folder.

Migration to ECMAScript Modules (ESM)

• Successfully migrated the entire codebase from CommonJS to ECMAScript Modules (ESM).
• Updated import statements and module syntax throughout the project to align with ECMAScript Modules.
• Replaced require with import and module.exports with export.
• Adjusted the package.json configuration to indicate ESM usage, setting the "type" field to "module".
• Transitioned from using nyc to c8 for generating coverage reports.

@ankitdas13 is this work not useful?

@gaganbiswas thanks for contributing man. Since you seem to be familiar with the codebase, would you be willing to maintain a sensible (hopefully temporary, see #407) fork of this lib? Me and my colleague @makwanahardik will be happy to help.

Honestly my hands are full right now, so I don't know how much time I can give. But I am willing to help in anyway possible since an updated lib is required for this.

@gaganbiswas , alright, good.

Depending on whether razorpay responds soon, we might have to maintain a usable fork after all. Obviously all your work would be a great starting point.

Cheers
