PYTHON-5166 Fix db.command bulkWrite bug

[ShaneHarvey]

There's a larger question here on if we should even be doing this behavior anymore at all but I'll open a new ticket to investigate that.

Sorry, unable to cherry-pick to v4.11, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout -b cherry-pick-v4.11-080c1c61212594e4de4792cf055b904a570c4359 v4.11

git fetch origin 080c1c61212594e4de4792cf055b904a570c4359

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 080c1c61212594e4de4792cf055b904a570c4359

3. You will likely have some merge/cherry-pick conflicts here, fix them and commit:

git commit -am {message}

4. Push to a named branch:

git push origin cherry-pick-v4.11-080c1c61212594e4de4792cf055b904a570c4359

5. Create a PR against branch v4.11. I would have named this PR:

"PYTHON-5166 Allow Database.command to run bulkWrite commands (#2164) [v4.11]"
