Bump Minimums OSes to suppress Xcode 14 warnings (#865)

This updates all deployment target minimums to the values supported by Xcode 14.
It removes spurious warnings of the form:

```
The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 10.0, but the range of supported deployment target versions is 11.0 to 16.2.99.
```
