Add support for running the test sub-command with the bisect script (#22796)

Example usage:

```bash
scala project/scripts/bisect.scala --jvm 17 -- --bootstrapped --releases 3.6.4-RC1-bin-20241120-bd07317-NIGHTLY... test smth.test.scala
```

`smth.test.scala`
```scala
//> using dep org.scalameta::munit::1.1.0
//> using platform js

class MyTests extends munit.FunSuite {
  test("foo") {
    assert(2 + 2 == 4)
  }
}
```
