(aws-lambda-python-alpha): Poetry 2+ unsupported in public.ecr.aws/lambda/python:3.10

### Describe the bug

Starting in poetry version 2, dulwich is default git client of poetry. Later versions of dulwich relies on `ssh` command having `-o SetEnv` option. However public.ecr.aws/lambda/python:3.10 has very old version of `ssh` - 2017 where this option is not supported.

### Last Known Working CDK Library Version

_No response_

### Expected Behavior

AWS Lambda Python docker image `python:3.10` is successfully built when using poetry 2+

### Current Behavior

Cannot use `PythonFunction` construct with python version 3.10 and poetry 2+.

### Reproduction Steps

Use [PythonFunction](https://docs.aws.amazon.com/cdk/api/v2/docs/@aws-cdk_aws-lambda-python-alpha.PythonFunction.html) construct with python runtime 3.10 and build arguments `POETRY_VERSION: 2.1.3`
```python
lambda_python.PythonFunction(
...
runtime=lambda_.Runtime.PYTHON_3_10,
bundling=lambda_python.BundlingOptions(
...
build_args={'POETRY_VERSION': 2.1.3}
),
)
```

### Possible Solution

There are 2 workarounds I can think of at the moment:
1. Use your own Dockerfile to build lambda, where you do
```Dockerfile
RUN yum install -y git
RUN poetry config system-git-client true
```
or use some newer docker image version where dulwich will work (I guess python:3.12 should work since it's using newer Amazon Linux 2023)

2. Add bundling command hook to do same thing as in step 1
```python
lambda_python.PythonFunction(
...
bundling=lambda_python.BundlingOptions(
...
command_hooks=CommandHooks(
before=lambda input, output: [
"yum install -y git",
"poetry config system-git-client true"
]
)
),
)
```

### Other information

_No response_

Start at the PythonFunction construct and its BundlingOptions, then reproduce a Python 3.10 build with POETRY_VERSION 2.1.3 using public.ecr.aws/lambda/python:3.10. Compare the available ssh client and Poetry configuration with newer runtime images or the proposed hooks; done means PythonFunction bundles successfully with Poetry 2+ on Python 3.10.
