chore(php): bump minimum to php 8.2 (#2611)

## Description

Requirement for #2610
to work, because `symfony/type-info` only support a minimum version of
PHP `8.2`.

I am fairly convinced that a bump from `8.1` to `8.2` can be done in a
minor version bump (compared to `7.4` to `8.1` which I did in a major
from `4.x` to `5.x` previously):
1. I have seen other packages do this (One example being [Symfony
6.1](https://symfony.com/blog/symfony-6-1-will-require-php-8-1))
2. I asked gemini:
   | Environment Change	| Package Version Bump | SemVer Rationale |
   | ------------------ | -------------------- | ---------------- |
| PHP 8.1 to 8.2 | Minor (e.g., 1.3.0) | Backward-Compatible Language
Bump: No new major incompatibilities were introduced between 8.1 and
8.2. |
| PHP 7.4 to 8.1 | Major (e.g., 2.0.0) | Backward-Incompatible Language
Bump: PHP 8.x introduced fundamental, breaking changes that cause 7.x
code to fail. |

Additionally PHP `8.1` will stop being supported in 1 month (security
support until 31 dec 2025) https://www.php.net/supported-versions.php
