bazel coverage ... , the coverage data cannot count code block execution times

### What version of rules_go are you using?

0.29.0

### What version of gazelle are you using?

0.23.0

### What version of Bazel are you using?

4.2.2

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

Yes

### What operating system and processor architecture are you using?
macos aarch64, also tested on Linux x86_64

### What did you do?

when running `bazel coverage ...` for my project, i get coverage data that only count whether a code block has been executed. like this
```
a/test.go:12.109,15.16 3 1
a/test1.go:19.2,19.36 1 1
a/test2.go:23.2,24.39 2 1
a/test3.go:67.16,70.3 2 0
```
the last element only count whether a code block has been executed

### What did you expect to see?
i want to get coverage data that can count the number of executions of code blocks.
like this
```
a/test.go:12.109,15.16 3 3
a/test1.go:19.2,19.36 1 2
a/test2.go:23.2,24.39 2 4
a/test3.go:67.16,70.3 2 0
```

Reproduce the issue with `bazel coverage ...` using rules_go 0.29.0, Gazelle 0.23.0, and Bazel 4.2.2 on a representative Go project, then compare the generated coverage data with the expected execution counts. Read the coverage-related rules_go and Bazel integration identified during reproduction. Done means coverage entries report execution counts rather than only zero or one.
