Add tunnel support for react native

[serglom21]

Currently, the tunnel config option does not work as it does for the browser SDK, even tho is advertised in our react native docs.

Could we enable this functionality on react native?

FYI - Discord is really interested in this feature - from the docs we expected this to work already.

@thenickreynolds Hi, thank you for the information,
this is not implemented in RN yet.

The appearance in the docs was a bug. This is supported in the browser SDK at the moment.
