Add examples using non-GET methods

[zxqx]

Since we link to the axios docs, we shouldn't have to document every single axios config option, but maybe it would be useful to add examples for POST, PUT, etc.

While this might be trivial for some, it really could be quite useful, for beginners like me I will keep this in mind to submit this as one of my first pull requests maybe? Good opportunity for beginners to contribute

@yashgada That'd be great -- will keep an eye out for that.
