Accept variable pinning

[qdm12]

Hi there,

Great linter. Although I prefer to use it by pinning the variable inside the for loop, before calling t.Parallel() for test cases and the linter detects it as invalid. Maybe you could add a rule for such thing? There are a few cases I can think of:

Pinning the variable before t.Run

func Test(t *testing.T) {
	t.Parallel()
	testCases := map[string]struct {
		n int
	}{
		"zero": {n: 0},
		"one":  {n: 1},
	}
	for name, testCase := range testCases {
		testCase := testCase
		t.Run(name, func(t *testing.T) {
			t.Parallel()
			t.Log(testCase.n)
		})
	}
}

Pinning the variable inside t.Run before t.Parallel()

func Test(t *testing.T) {
	t.Parallel()
	testCases := map[string]struct {
		n int
	}{
		"zero": {n: 0},
		"one":  {n: 1},
	}
	for name, testCase := range testCases {
		t.Run(name, func(t *testing.T) {
			testCase := testCase
			t.Parallel()
			t.Log(testCase.n)
		})
	}
}

Pretty much pinning the variable between the for and the t.Parallel() should pass the linting, although some additional checks might be needed such as if the pinned variable has a different name etc.
