Dhruv Manilawala 6e9ff445fd Insert the cells from the start position (#15398)
## Summary

The cause of this bug is from
https://github.com/astral-sh/ruff/pull/12575 which was itself a bug fix
but the fix wasn't completely correct.

fixes: #14768 
fixes: https://github.com/astral-sh/ruff-vscode/issues/644

## Test Plan

Consider the following three cells:

1.
```python
class Foo:
    def __init__(self):
        self.x = 1

    def __str__(self):
        return f"Foo({self.x})"
```

2.
```python
def hello():
    print("hello world")
```

3.
```python
y = 1
```

The test case is moving cell 2 to the top i.e., cell 2 goes to position
1 and cell 1 goes to position 2.

Before this fix, it can be seen that the cells were pushed at the end of
the vector:

            contents: "def hello():\n    print(\"hello world\")",
        },
    },
]
```

After the fix in this PR, it can be seen that the cells are being pushed
at the correct `start` index:
