Fixed Upgrade Facebook Api

[TnT]

Affected version

v2.2.6 Patch 1

As Facebook is shutting off its Graph API v3.3 on 03 August, 2021, please upgrade to at least Graph API v4.0 (v11.0 is actual).

Seems to be used here: XF\ConnectedAccount\ProviderData\Facebook

This would always probably have been okay because if you try to use an old version of the Graph API it would simply forward requests to the first still-supported version.

That said, we can omit the version string entirely and it will always attempt to use the latest version now. This presents a risk in case there are major changes in the future but our use case is so limited (we only really need name and maybe email) that it should be fine.
