[Bug] fetchTimeout does not handle network latency

[edsrzf]

Current Behavior
If I specify fetchTimeout in the init method, the timeout only comes into effect when the request fails. If the request is simply slow, due to network latency, the timeout doesn't trigger.

Expected Behavior
The timeout should be triggered when the fetch request is slow.

Steps to Reproduce

• Initialize Transifex Native using a fetchTimeout.
• Simulate network latency through a proxy or other developer tools. The latency must be longer than the configured timeout.
• Observe that translation-fetching continues past the timeout.

Possible Solution
Add a timeout to the axios.Get call.

Possible Implementation
I would use an Axios AbortController with a timeout based on fetchTimeout, as documented on this page: https://axios-http.com/docs/cancellation
