Describe the bug

This is a follow-up issue to the functionality introduced in PR #4343 (thank you @tmm!).

Metamask Mobile uses the io.metamask.mobile rdns. This means that using wagmi via the metamask browser on mobile with multiInjectedProviderDiscovery and the metamask connector initialized will still result in duplicated Metamask connectors.

Link to Minimal Reproducible Example

https://wagmi-tests-2.vercel.app/

Steps To Reproduce

1. Open Metamask Mobile on iOS or Android
2. Open https://wagmi-tests-2.vercel.app/
3. Two metamask connectors show up instead of one, because the io.metamask.mobile rdns is not filtered.

Nice find! If someone wants to work on this, all they need to do is add readonly string[] to rdns and update a few places in createConfig.ts and hydrate.ts (follow the type errors).
