Issue:
Cannot retrieve cell value when column or row are zero
### Describe the bug

You cannot retrieve a cell value when row or column are zero since there is a `if not` check that prevents the call to go thru.

```    def cell_with_row_with_column(self,column: int, row: int) -> CellWithRowWithColumnRequestBuilder:
        """
        Provides operations to call the cell method.
        param column: Usage: column={column}
        param row: Usage: row={row}
        Returns: CellWithRowWithColumnRequestBuilder
        """
        if not column:
            raise TypeError("column cannot be null.")
        if not row:
            raise TypeError("row cannot be null.")
        from .cell_with_row_with_column.cell_with_row_with_column_request_builder import CellWithRowWithColumnRequestBuilder

        return CellWithRowWithColumnRequestBuilder(self.request_adapter, self.path_parameters, column, row)
```

### Expected behavior

The call should support zeros since indexing of columns and rows are zero-based.

### How to reproduce

```client.drives.by_drive_id(drive_id).items.by_drive_item_id(item_id).workbook.worksheets.by_workbook_worksheet_id(worksheet_id).cell_with_row_with_column(0, 0).get()```

### SDK Version

1.4.0

### Latest version known to work for scenario above?

_No response_

### Known Workarounds

None

### Debug output

```self = <msgraph.generated.drives.item.items.item.workbook.worksheets.item.workbook_worksheet_item_request_builder.WorkbookWorksheetItemRequestBuilder object at 0x10a1ec810>
column = 23, row = 0

    def cell_with_row_with_column(self,column: int, row: int) -> CellWithRowWithColumnRequestBuilder:
        """
        Provides operations to call the cell method.
        param column: Usage: column={column}
        param row: Usage: row={row}
        Returns: CellWithRowWithColumnRequestBuilder
        """
        if not column:
            raise TypeError("column cannot be null.")
        if not row:
>           raise TypeError("row cannot be null.")
E           TypeError: row cannot be null.
```

### Configuration

OS: macOS Sonoma
Arch: ARM64

### Other information

Pull request:
Closes https://github.com/microsoftgraph/msgraph-sdk-python/issues/795


Note that

`if not column` is falsy even if colum exists and is zero, using i`f column is None` will check that column is null in a better way in this case:


The generated code behavior is now adjusted from
```python
if not body:
    raise TypeError("body cannot be null.")
request_info = self.to_patch_request_information(
        body, request_configuration
    )

```

To
```python

if body is None:
    raise TypeError("body cannot be null.")
request_info = self.to_patch_request_information(
        body, request_configuration
    )
```


And the same applies in all areas including drive items
