unnecessary error message when ignoring the upper bound of platform requirements

[dg]

When option --ignore-platform-req=php+ is used, it still prints the error message like Cannot use texy/texy's latest version v3.2.0 as it requires php 8.1 - 8.3 which is not satisfied by your platform., although it does install the library.

composer.json:

{
    "config": {
        "platform": {
            "php": "8.4"
        }
    }
}

Run:

composer --ignore-platform-req=php+ require texy/texy

I've tested this locally with Composer version 2.6.5 and PHP 8.2.

Command	Warning shown?	Version installed
composer require texy/texy	Yes	3.1.7
composer --ignore-platform-req=php require texy/texy	No	3.2.0
composer --ignore-platform-req=php+ require texy/texy	Yes	3.2.0

According to the documentation for --ignore-platform-req, using php+ changes the restraint from =8.4 to >=8.4. Version 3.2.0 of the texy/texy package requires PHP versions 8.1-8.3, which is not satisfiable with a constraint of >=8.4. Printing the warning here seems sensible to me.

I think the bug here is not about the warning message, but instead that when specifying php+ we get an "incorrect" version of the package installed. I would expect version 3.1.7 to be installed (which has a PHP constraint of >=7.1), not version 3.2.0 (which has a PHP constraint of 8.1-8.3).

@fredden --ignore-platform-req does not affect the value in config > platform, but the value in require > php in the installed package. So it doesn't affect 8.4, but the value of 8.1 - 8.3 here https://github.com/dg/texy/blob/master/composer.json#L14

Yeah I see what you mean, the first line of output there is not needed, and actually incorrect as it ends up using it anyway. I'll see if we can get rid of that.

$ composer --ignore-platform-req=php+ require texy/texy
