libsodium and ext-sodium are absent in my Elastic Beanstalk PHP 8.2 platform

Question

I have an Elastic Beanstalk environment. The platform is `PHP 8.2 running on 64bit Amazon Linux 2023/4.0.2`. In my composer file I have a dependency on `ext-sodium`. I've noticed that sodium was added in AL2023 since version [2023.2.20230920](https://docs.aws.amazon.com/linux/al2023/release-notes/relnotes-2023.2.20230920.html). PHP platform [version 4.0.2](https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platform-history-php.html#platform-history-2023-11-15) uses AL2023 version 2023.2.20231016 which is even higher. My question is what I am missing in getting libsodium and php sodium extension while deploying my application?

I tried to enable extension by adding Elastic Beanstalk config file:

```
files:
  "/etc/php.d/sodium.ini":
    mode: "000755"
    owner: root
    group: root
    content: |
      extension=sodium.so
```

but no luck, I got next error:

> [ERROR] An error occurred during execution of command [app-deploy] - [Install composer dependencies]. Stop running the command. Error: installing composer dependencies failed with error: Command /bin/sh -c composer.phar install --no-ansi --no-interaction --no-dev failed with error exit status 2. Stderr:PHP Warning:  PHP Startup: Unable to load dynamic library 'sodium.so' (tried: /usr/lib64/php8.2/modules/sodium.so (/usr/lib64/php8.2/modules/sodium.so: cannot open shared object file: No such file or directory), /usr/lib64/php8.2/modules/sodium.so.so (/usr/lib64/php8.2/modules/sodium.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I've added this config in my app:

`.ebextensions/libsodium.config`

```
commands:
    command1:
      cwd: /tmp
      command: wget https://download.libsodium.org/libsodium/releases/LATEST.tar.gz
    command2:
      cwd: /tmp
      command: tar -xvzf LATEST.tar.gz
    command4:
      cwd: /tmp/libsodium-stable
      command: ./configure
    command5:
      cwd: /tmp/libsodium-stable
      command: make && make check
    command6:
      cwd: /tmp/libsodium-stable
      command: sudo make install
    command7:
      cwd: /tmp/libsodium-stable
      command: sudo pecl install -f libsodium
```
