Consider changing Composer package type to "phpcodesniffer-standard"

[rodrigoprimo]

This PR suggests changing the Composer package type to enable automatic standard registration via the PHPCSStandards Composer installer plugin.

Problem/Motivation

Composer allows declaring a package's type. This package currently uses "config" as its type.

There is a Composer plugin that can install custom PHP_CodeSniffer standards: https://github.com/PHPCSStandards/composer-installer

This plugin is part of the PHPCSStandards organisation, which is the new official home of PHP_CodeSniffer.

For this installer to work, the package type needs to be set to phpcodesniffer-standard.

There are already over 470 packages that use this type. As a side benefit, using this type will allow end-users to more easily find other external PHP_CodeSniffer standards that may be interesting to them when searching on Packagist.

Proposed changes

Change the type in composer.json from "config" to "phpcodesniffer-standard".

This will in no way change the existing behavior of this package for users that do not include the Composer plugin mentioned above in their projects' composer.json.

Thank you for bringing this up!

Since it mainly improves compatibility with the PHPCSStandards Composer installer and does not change the behavior for users who do not use the plugin, it seems like a sensible adjustment!
