aws_s3_deployment: Files deleted when deployment bucket is used in sequence

### Describe the bug

I have a stack for which I wish to deploy two scripts on S3.

I have two files under `../assets` which I want both deployed at the top level of the created `AssetBucket`. What I'm observing instead is that only one of the files ends up being deployed, and it seems like it's random, sometimes the corresponding to `SINGLE_ENTRYPOINT_FILENAME` is deployed, sometimes `ENTRYPOINT_FILENAME`.

Not sure if there's some sort of race condition going on.

### Expected Behavior

Both files should be deployed

### Current Behavior

Only one of the resource files actually ends up on S3

### Reproduction Steps

Here's how I'm trying to accomplish that:

```python
from aws_cdk import (
Stack,
aws_s3_deployment as s3_deploy,
)

DIRNAME = os.path.dirname(__file__)

class EntrypointAssetStack(Stack):
"""Creates the needed resources for the entrypoint assets on S3."""

def __init__(
self,
scope: Construct,
construct_id: str,
**kwargs,
) -> None:
super().__init__(scope, construct_id, **kwargs)

# Create an asset bucket where we upload the entry point script
# TODO: Trying to add removal policy here messes up bucket policy downstream, can we fix this?
asset_bucket = s3.Bucket(
self,
"AssetBucket",
# removal_policy=RemovalPolicy.DESTROY,
# auto_delete_objects=True,
block_public_access=s3.BlockPublicAccess.BLOCK_ALL,
versioned=True,
)

# Omitted a point where I create a policy for the asset bucket, asset_bucket_policy

entrypoint_deployment = s3_deploy.BucketDeployment(
self,
"DeployMultiEntryPoint",
destination_bucket=asset_bucket,
sources=[
s3_deploy.Source.asset(
path=os.path.join(DIRNAME, "..", "assets"),
exclude=["**", f"!{ENTRYPOINT_FILENAME}"],
)
],
retain_on_delete=True,
)
entrypoint_deployment.node.add_dependency(asset_bucket_policy)

single_entrypoint_deployment = s3_deploy.BucketDeployment(
self,
"DeploySingleWorkerEntryPoint",
destination_bucket=asset_bucket,
sources=[
s3_deploy.Source.asset(
path=os.path.join(DIRNAME, "..", "assets"),
exclude=["**", f"!{SINGLE_ENTRYPOINT_FILENAME}"],
)
],
retain_on_delete=True,
)
single_entrypoint_deployment.node.add_dependency(asset_bucket_policy)
```

Start with the aws_s3_deployment.BucketDeployment and Source.asset entry points described in the reproduction, then run the two sequential deployments against one bucket. Trace how each deployment handles existing objects and verify the behavior with a focused regression test; done means both entrypoint files remain in the bucket after deployment.
