unclear how to consistently get all of the log output from tests

### What version of rules_go are you using?

0.50.1

### What version of gazelle are you using?

0.39.1

### What version of Bazel are you using?

7.3.1

### Does this issue reproduce with the latest releases of all the above?

Yes.

### What operating system and processor architecture are you using?

macOS arm

### What did you do?

Tried to run all of the tests in a package without caching with verbosity turned up to see all of the `t.Logf` lines in it.

I tried both with `-test.v`, and `test.count` and without:

```
$ bazel test --cache_test_results=no --test_output=all //foobar/baz:baz_test
```

```
$ bazel test --cache_test_results=no --test_output=all --test_arg="-test.v" //foobar/baz:baz_test
```

```
$ bazel test --cache_test_results=no --test_output=all --test_arg="-test.count=1" //foobar/baz:baz_test
```

```
$ bazel test --cache_test_results=no --test_output=all --test_arg="-test.count=1" --test_arg="-test.v" //foobar/baz:baz_test
```

### What did you expect to see?
All of the tests enumerated and all the log lines run by the tests like the usual `go test -v` command.

Output like:

```
$ go test -v .
=== RUN TestGoldenPath
baz_test.go:23: I'm here
```

### What did you see instead?

The versions with `-test.v` or `-test.count` always just print (with `--cache_test_results=no --test_output=all` included, of course) will only get you the

```
//foobar/baz:baz_test PASSED in 1.0s
```

Dropping those and only run `bazel test --cache_test_results=no --test_output=all` will get you only:

```
==================== Test output for //foobar/baz:baz_test:
PASS
================================================================================
```

with the usual

```
//foobar/baz:baz_test PASSED in 1.0s
```
after it

Start by reproducing the reported commands for //foobar/baz:baz_test, comparing Bazel's output with `go test -v .`; the example points to baz_test.go:23. Check how `t.Logf` output is handled under `--test_output=all`, `-test.v`, and `-test.count=1`. Done means the documented command consistently shows all test names and log lines without relying on caching.
