`--test_output=streamed` does not stream the logs when executing remotely

### Description of the bug:

If running a test with a remote executor

```
bazel test --remote_executor=grpcs://remotebuildexecution.googleapis.com --test_output=streamed //path/to:test
```

No logs are actually streamed to the terminal:

```
INFO: Analyzed target //incode/experimental/users/alexanderfaxa:sleep_forever_test (0 packages loaded, 0 targets configured).
[4 / 5] Testing //experimental/users/faximan:sleep_forever_test; 28s
# nothing
```

Eventually, the test times out and then dumps the whole log to my terminal. If I ctrl-c abort the process _while the test is running_, the logs are as far as I know lost forever.

### Which category does this issue belong to?

### What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

_No response_

### Which operating system are you running Bazel on?

Linux

### What is the output of `bazel info release`?

release 8.4.0

### If `bazel info release` returns `development version` or `(@non-git)`, tell us how you built Bazel.

### What's the output of `git remote get-url origin; git rev-parse HEAD` ?

```text
Private repo
```

### If this is a regression, please try to identify the Bazel commit where the bug was introduced with bazelisk --bisect.

### Have you found anything relevant by searching the web?

There is https://github.com/bazelbuild/bazel/issues/19428 which is somewhat related.

Some people there are wondering whether `--test_output=streamed` will force local execution. In my experience it does not.

### Any other information, logs, or outputs that you want to share?

_No response_

Start by reproducing the supplied bazel test command with the remote executor and --test_output=streamed, then compare the behavior with issue #19428. Done means test logs appear in the terminal while the remote test is still running, including before an abort or timeout.
