Issue: Boolean valued images loaded from disk, when converted to torch int/float tensor, the True valued pixels gets converted to 255 instead of 1
Labels: triaged,module: boolean tensor

### 🐛 Describe the bug

Boolean valued images loaded from disk, when converted to torch int/float tensor, the True valued pixels gets converted to 255 instead of 1

**Step-by-step procedure:**
- Load a boolean-valued image from disk using PIL.Image.open.
- Convert image to boolean numpy array
- Convert to torch.tensor
- Convert to torch int / float tensor
- The `True` valued pixels in the original image now have a value of `255`, instead of `1`

**Minimal reproducible code**
```python
print_img_info = lambda desc, inp_img: print(
    f"{desc} | type: {type(inp_img)} dtype: {inp_img.dtype}, max: {inp_img.max()}, min: {inp_img.min()}"
)

img = np.array(Image.open(img_path))        
print_img_info("orignal image", img)
# orignal image | type: <class 'numpy.ndarray'> dtype: bool, max: True, min: False

imgT = torch.tensor(img)
print_img_info("torch image", imgT)
# torch image | type: <class 'torch.Tensor'> dtype: torch.bool, max: True, min: False

imgTInt = imgT.to(torch.int)
print_img_info("torch image int", imgTInt)
# torch image int | type: <class 'torch.Tensor'> dtype: torch.int32, max: 255, min: 0

imgTFloat = imgT.to(torch.float)
print_img_info("torch image float", imgTFloat)
# torch image float | type: <class 'torch.Tensor'> dtype: torch.float32, max: 255.0, min: 0.0
```
Note that the output of every print statement is commented in the next line. Notice that the int/float tensor's max pixel value is 255 instead of 1.

### Versions

I tested the attached zip on many of my colleagues' machines. I was able to reproduce the issue on all of them except for one.
Attaching some of those environments here. I have added the PIL library versions for these environments as well.
