Not compatible with axios 1.7.9

[ronaldcreutz-vw]

Thanks a lot for that helpful library to the contributers!

Since the last update of axios library to 1.7.9 the aws4-axios interceptor isn't compatible and build fails.

e.g.
Argument of type '(config: InternalAxiosRequestConfig) => Promise<InternalAxiosRequestConfig>' is not assignable to parameter of type '(value: InternalAxiosRequestConfig) => InternalAxiosRequestConfig | Promise<InternalAxiosRequestConfig>'.
Types of parameters 'config' and 'value' are incompatible.
