`laminas/laminas-cache` is specified in both `require` AND `require-dev` sections of `composer.json`

Bug Report

Q	A
Version(s)	2.1.0

Summary

Reviewing these cache packages, I noticed the titular problem which I was previously told explicitly to NOT do:

• composer update --no-dev loads dependencies from require-dev key composer/composer#3742 (comment).

Current behavior

composer install --no-dev installs laminas/cache 3.0.x-dev and not 3.0. Whereas this may suffice for the use case here as neither the lock file nor require-dev section SHOULD be read during installation as a library, this isn't guaranteed as noted om the above issue.

How to reproduce

Check out repository locally and run composer install --no-dev.

Expected behavior

A package should appear only in require OR require-dev and not both.

This is still a thing due to the fact that I had to provide some kind of pre-release compatibility.
Meanwhile, we can just drop it.
Will do that with PHP 8.2 support PR in the next couple of minutes.
