Remove duplicated position for task's status field (#11998)

In this PR:

- Set the default position for the DONE option of the task's status
option to `2` instead of `1`, which was the same as `IN_PROGRESS`
option's position.
- Write a command to prevent position duplicates in the database for the
task's status field.

What I've checked before setting this PR as ready to be reviewed:

- De-duplicating the position solves the issue and it's possible to edit
the field (solves the related issue)
- The upgrade command de-duplicates the position for each workspace.
There are no more DONE options with `position=2`. I ran the upgrade
command on the `database-snapshot-manager` dataset.
- Suspended workspaces aren't fixed

To test the script:

```ts
const scannedPositions = new Set();
let biggestPosition = -1;

// Sort options by position for consistent processing
const sortedOptions = [
  { name: 'a', position: 2 },
  { name: 'b', position: 1 },
  { name: 'c', position: 1 },
  { name: 'd', position: 2 },
].sort((a, b) => a.position - b.position);

for (const option of sortedOptions) {
  if (scannedPositions.has(option.position)) {
    option.position = biggestPosition + 1;
  }

  biggestPosition = Math.max(biggestPosition, option.position);
  scannedPositions.add(option.position);
}

console.log('Sorted options:', sortedOptions);
```
