Added timeout fix for axiosInstance

[AlexZeDim]

I do not remember, have I created this issue or not, but defaultAxios doesn't have timeout at all.

What problem it could generate? If battle.net endpoint somehow doesn't reply you back or packets will be missing, you will never receive the response at all.

For example, if I request data about 10 characters one-by-one, and on the 3rd character request I don't receive a reply from API, well it will block the main thread. Literally forever.

So this little string adds a timeout to axios instance, which will reject the request by timeout. I also understood that according to this issue the axios will be removed by the native fetch method, which doesn't support the timeouts at all. But by creating this pull request I just notify that the problem exists and it deserves any attention.

Okay, to be honest, according to this issue thread in the fetch repo most of the devs think about the timeout option as userland, so in that case, it should be implemented manually.

@AlexZeDim thanks for the PR! Yeah, this is something that is definitely missing and it badly needs to be fixed.

In a later iteration I'll make timeout value configurable via an optional property, for now I'm merging as-is. Npm update will arrive later today.
