fix: uikit-utils should be permissive to replaced global Promise

[grizio]

Some environments replace global.Promise with a polyfill at startup. I happen to encounter this case using new-relic agent for monitoring reasons.

This commit makes the use of Promise vs function more permissive to these replaced Promises.

Here the email I prepared:

Working with new-relic and currently installing Sendbird in our application, I encountered an incompatibility between the two libraries. I created a fix, visible here: https://github.com/sendbird/sendbird-uikit-react-native/compare/main...grizio:sendbird-uikit-react-native:fix/permissive-promise?expand=1

For the moment, I had to implement several workarounds (for now in channel creation screen and open channel screen) to avoid falling in this part of the library and I think this could happen to others.

Is it possible to setup a CLA? Otherwise, if you have other way to fix this issue, I would gladly accept.
