use_build_context_synchronously false negative when checking mounted for different BuildContext

[AhmedLSayed9]

Describe the issue
When using multiple BuildContext, use_build_context_synchronously is not triggered if I checked .mounted for a different BuildContext.

To Reproduce

Future<void> f1(BuildContext context, BuildContext anotherContext) async {
  await Future<void>.delayed(Duration.zero);
  // print(context.size);  //this triggers fine
  if (anotherContext.mounted) print(context.size);
}

Expected behavior
The linter should trigger as I've not checked for context.mounted.

Good catch 😁 Don't expect this to be fixed any time soon. I think I'm just going to document this as a limitation of the rule.
