Up front interceptor config

[keawade]

Howdy @benhason1, I've been happily using this library in my work for a while now. Thanks!

In my work I've found myself needing to configure Axios interceptors up front but not finding a good way to do that between NestJS's constraints and the current implementation of this module. This PR aims to provide a way for users to configure Axios interceptors via the Module registration.

To do this, this PR introduces a breaking change to how the module is configured. The module options object is no longer the Axios configuration object but rather a module options object of

type HttpModuleOptions = {
  axiosConfig: AxiosRequestConfig;
  axiosRetryConfig: IAxiosRetryConfig;
  interceptors: {
    // Full details added to documentation in the readme
    request: { ... };
    response: { ... };
  };
}

I'm not a huge fan of breaking changes but I found myself preferring this approach to overloading the existing configuration object. Since I was splitting something out from the shared Axios and Axios Retry config object anyways I figured it might be worth additionally explicitly disentangling those two configuration objects as well which should have the additional benefit of lowering the risk of name collisions between the two libraries.

I refactored the module to use NestJS's ConfigurableModuleBuilder make it much simpler for me to add the new module configuration options.

This should also mean you won't have to maintain your own implementations of .register and .registerAsync any more as that is now handed off to NestJS's builder.

I kept the bulk of these changes in the first commit to help make it easier to review.

---

To make sure I didn't break anything unexpected I added tests of the module construction. I used vitest as it is one of the most Just Works TM solutions I'm aware of.

---

It appeared the documented "better axios stack trace" is no longer implemented by this library directly so I removed references to it in the documentation. As far as I can tell the related issues in the Axios repo have been resolved and improvements to the stack trace have been merged.

Let me know if you have any questions or suggestions for how to improve this PR! Thanks again!

Just added a workflow to run tests against the three node versions that are receiving updates currently. You can see an example of what it will look like on this test PR here: keawade#1

Hey @benhason1 👋. Bumping this in the hopes it could get some discussion or maybe even a merge. 😄
