Enable UDS tests on Windows

[drinkcat]

AF_UNIX support landed in Dart SDK 3.11.0 (Flutter 3.41.0), so the
Windows skip in testUds is no longer needed.

Closes #735

• dart-lang fix dart-lang/sdk@e50d3b9
• I didn't bump the SDK requirement. If users want the feature on Windows, they need to upgrade. Otherwise, the current 3.8.0 should be fine. And I believe you mostly test using stable Flutter releases which should be way past 3.41.0.

Oh, I was hoping CI would run tests on Windows, but that doesn't seem to be the case. I can try to run locally.

(I have tested this, but in a complete application)

[drinkcat]

I added a second commit, necessary to fix the tests (Windows doesn't like to remove directories when files are still in use).

Flutter 3.41.0 (Dart 3.11.0):

CI is red due to google/googleapis.dart#746, will have to wait for resolution of that first.

[drinkcat]

(I also updated the README, thought it'd be nice to mention 3.11.0 is needed for UDS support on Windows)

[drinkcat]

oh nice, I'll have a look at the CI failures

https://github.com/grpc/grpc-dart/actions/runs/27000163712/job/80522388710?pr=828

❌ test\server_handles_broken_connection_test.dart: the client interrupting the connection does not crash the server (over uds) (failed)
TimeoutException after 0:00:30.000000: Test timed out after 30 seconds. See https://pub.dev/packages/test#timeouts
dart:isolate _RawReceivePort._handleMessage

I tested locally (same dart SDK) and it seems to be a flake... 1/20 so far...

I was hoping CI would run tests on Windows

It is running them - or what do you mean?

CI ended up running yes! I think something else was broken at the time.
