[Bug] `ld.so.cache` is out of date, leading to `libpython3.10.so.1.0: cannot open shared object file` error

### Expected Behavior

I expected that while installing the [poetry package manager](https://python-poetry.org/), the poetry install process would find all Python shared libraries.

### Actual Behavior

Instead the error `1.119 /home/.local/share/pypoetry/venv/bin/python3: error while loading shared libraries: libpython3.10.so.1.0: cannot open shared object file: No such file or directory` is shown.

This install process worked in the function runtime v3 images, and seems to be caused by `ld.so.cache` being out of date. A work-around for the issue is running `ldconfig`.

### Steps to Reproduce

I'm going to provide four example Dockerfiles.

The first Dockerfile demonstrates that one can install Poetry in this manner using a v3 runtime, and Python 3.9.

The second Dockerfile demonstrates that this does not work in a v4 runtime, again using Python 3.9.

The third Dockerfile demonstrates a work-around: if you run `ldconfig` before installing poetry, it works again.

The fourth Dockerfile demonstrates that bug can occur in v4 using Python 3.10, in order to demonstrate the bug with a supported version of the runtime and a supported version of Python.

### Relevant code being tried

```shell
# This works in v3
FROM mcr.microsoft.com/azure-functions/python:3.0-python3.9
RUN curl -sSL https://install.python-poetry.org | python3 -; \
saved=$?; \
cat /poetry-*.log; \
exit $saved
```

```shell
# This fails in v4, only changing runtime version
FROM mcr.microsoft.com/azure-functions/python:4-python3.9
RUN curl -sSL https://install.python-poetry.org | python3 -; \
saved=$?; \
cat /poetry-*.log; \
exit $saved
```

```shell
# This works in v4, using ldconfig workaround
FROM mcr.microsoft.com/azure-functions/python:4-python3.9
RUN ldconfig
RUN curl -sSL https://install.python-poetry.org | python3 -; \
saved=$?; \
cat /poetry-*.log; \
exit $saved
```

```shell
# This fails, while using a supported version of Python
FROM mcr.microsoft.com/azure-functions/python:4-python3.10
RUN curl -sSL https://install.python-poetry.org | python3 -; \
saved=$?; \
cat /poetry-*.log; \
exit $saved
```

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/home/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Poetry (2.1.3) is installed now. Great!

To get started you need Poetry's bin directory (/home/.local/bin) in your `PATH`
environment variable.

Add `export PATH="/home/.local/bin:$PATH"` to your shell configuration file.

Alternatively, you can call Poetry explicitly with `/home/.local/bin/poetry`.

You can test that everything is set up by executing:

`poetry --version`

### Where are you facing this problem?

Local - Core Tools

### Function app name

_No response_

### Additional Information

I suggest that `ldconfig` be run in the base image so that others who want to install Poetry can do so without encountering this error.

まず Azure Functions Python v3 および v4 のベースイメージのビルド定義を見つけ、issue に記載されている4つの Dockerfile ケースを、ldconfig の workaround を含めて再現します。共有ライブラリのキャッシュがどのように生成されるかを比較します。完了の条件は、サポート対象の Python イメージで、Poetry インストーラーが手動の workaround なしに libpython3.9.so.1.0 と libpython3.10.so.1.0 を見つけられることです。
