Update PHP_CodeSniffer repository link and schema URL

[rodrigoprimo]

PHP_CodeSniffer has moved to a new GitHub organization. The squizlabs/PHP_CodeSniffer repository is now archived and the project is actively maintained at https://github.com/PHPCSStandards/PHP_CodeSniffer.

Additionally, PHP_CodeSniffer now provides a canonical permalink for the XML schema used in the xsi:noNamespaceSchemaLocation attribute of ruleset files. This replaces the previous raw.githubusercontent.com URL with https://schema.phpcodesniffer.com/phpcs.xsd.

• Publish XSD file(s) on stable URL PHPCSStandards/PHP_CodeSniffer#1094

Poem

🐰 Our ruleset hops to a new home so grand,
With schema and links from PHPCSStandards' hand,
No logic did change, just breadcrumbs we find,
Pointing to places of canonical kind! ✨

Code Review

This pull request updates the PHP_CodeSniffer schema and repository URLs to their new official locations. A critical issue was identified in the composer.json file where duplicate require-dev and config sections will cause composer commands to fail, requiring these blocks to be merged.

[gemini-code-assist]

The composer.json file is invalid because it contains duplicate keys (require-dev and config). This will cause composer commands to fail and must be fixed.

Please resolve this by merging the duplicate sections. For instance, the two require-dev blocks should be combined into one. When doing so, you'll need to choose the correct version for packages like wp-coding-standards/wpcs, which is specified with both ^3.0 and ^3.1.
