Bruno Barbieri aeaf286c77 - Origin header check shouldn't be case sensitive (#27827) ...

Summary:
Based on [this](https://stackoverflow.com/a/5259004), header names are not case sensitive.
That means that it's valid to pass a header `Origin` or `origin`.

With the current implementation. on Android only, if you pass `Origin`, it will get overwritten by the default origin.

This made me waste a lot of time debugging a problem while trying to connect to a websockets server that required an `origin` header and my implementation was working fine in iOS but not on Android, so I'm suggest changing the logic a little bit to take that into account.

## Changelog

[Android] [Fixed] - Support for case insensitive "Origin" headers for Websockets
Pull Request resolved: https://github.com/facebook/react-native/pull/27827

Test Plan:
Here's a screenshot of that shows the issue before the fix (`Origin` header set, but getting overridden)

The fix is not that easy to test since it requires a public websocket server that checks for a custom Origin header, but I think the code changes are very small and clear.
