Forcing another session to log out does not support WebAuthn

### Steps to reproduce

Where are you starting? What can you see?

User Settings -> Security -> My Sessions -> Tap on a session -> Tap on "Sign out this session"

Then, by coincidence, it requires me to re-authenticate with my social identity provider, in this case GitHub.

GitHub then requires me to use my security key, because I use 2FA with GitHub.

I tap the use security key button in the web page.
It says "authentication failed", despite using it earlier to sign into this device.

Other notes:

I have experienced this with the Cisco AnyConnect app. We had to change our configuration so the iOS app uses a slightly different web view technology.

Something about how `SFSafariWebView`

Element has no control on what or how the scripts run on a social login provider. This issue likely will only be resolved by switching the web view technology that comes up when tapping "Sign out this session".

### Outcome

#### What did you expect?

I expect to be able to use my security key to authenticate with GitHub and then return to Element's UI to remove the session.

#### What happened instead?

I was blocked
