Fix connectorImages examples to use RDNS format (#453)

* Fix connectorImages examples to use RDNS format

- Replace 'metaMask' with 'io.metamask'
- Replace 'coinbaseWallet' with 'io.coinbase'
- Replace 'phantom' with 'app.phantom'
- Keep 'walletConnect' and 'appKitAuth' as-is (no RDNS found)

Updates examples in shared options and React Native documentation
to match actual AppKit implementation requirements.

* Update connectorImages documentation to support both RDNS and normal IDs

- Add explanatory text about dual approach for connector identification
- EIP6963 wallets use RDNS format (io.metamask, io.coinbase, app.phantom)
- Other wallets use normal connector IDs (walletConnect, injected, appKitAuth)
- Update all examples across Wagmi, Ethers, and Solana adapters
- Address reviewer feedback from svenvoskamp on PR #453
