PHPCompatibilitySymfonyPolyfillPHP56: update ruleset for PHPCompatibility 10.0-alpha1

Looks like one function call would at the very least run into a warning: https://3v4l.org/v3mZE
Having said that, it would need a combination of Mbstring function overload being into effect + Mbstring not being available for this warning to be hit, which is probably why nobody ever reported it to Symfony.

All in all, not our concern, but a bug in the Polyfill, so let's just ignore it.

PHPCompatibilitySymfonyPolyfillPHP72: update ruleset for PHPCompatibility 10.0-alpha1

Two of the polyfilled functions have since been deprecated by PHP itself. As they are polyfilled by the Symfony PHP 7.2 polyfill, we can ignore the deprecation though.

Includes bug fix for a faulty test.

PHPCompatibilitySymfonyPolyfillPHP80: update ruleset for PHPCompatibility 10.0-alpha1

As of PHPCompatibility 10.0.0, we detect and handle the use of PHP 8.0 attributes (though I expect how to still change a little more).
In this case, an attribute is applied to the polyfill for the Attribute class, so we need to ignore that attribute ;-)

Version 2.0.0-alpha1 / Update for PHPCompatibility 10.0.0-alpha1

This update accounts for the following changes:

• Composer:
  • Update the version for the PHPCompatibility dependency.
    The @dev version number suffix should ensure that the PHPCompatibility 10.0.0-alpha1 version can be installed, even if the project minimum stability does not specifically allow for dev versions.
  • Remove the DealerDirect Composer PHPCS plugin dependency.
    This plugin will now automatically be installed as it is a dependency of PHPCSUtils and therefore of PHPCompatibility itself.
    Not having it set as an explicit dependency here, will prevent potential future conflicts with the supported versions of the plugin.
  • Removed the suggest section.
    The DealerDirect plugin no longer needs to be suggested and after two years, people should have gotten the message about using the roave/security-advisories.
• Readme:
  • Updated the minimum PHP and PHPCS requirements.
  • Updated the installation instructions for the 2.0.0-alpha1 release (being a dev release).
  • Updated the installation instructions to no longer mention adding a Composer plugin to sort out the PHPCS installed_paths.
  • Added upgrade instructions.
  • Added section about funding.
  • Use link list for links used multiple times.
  • Minor other tweaks after critical read-through of the README.
• CI:
  • Continue testing against dev-develop.
  • Prevent builds failing on low PHP versions on the recommendation to use a more recent PHP version.
