usage of deprecated header: Pragma

[Benjamin Hallion]

I'v been experimenting with this sweet library, and noticed the usage of the Pragma header.
While searching about it, I found out it is deprecated. I had to add it to my CORS allowed headers.
Perhaps you should consider removing it ?

Found on axios-cache-interceptor version "1.2.0"

Cheers

Pragma was added to ensure cross compatibility with older browsers. You can solve it the same way as #471.
