[Maintenance] [XML2PHP] convert service config from .xml to .php

[crydotsnake]

Issue: Sylius/Sylius#18490

[crydotsnake]

Since we are migrating the service config files from XML to PHP do we still need .xml in the FILE_PATTERNS array in the rename-plugin script? 🤔:

PluginSkeleton/bin/rename-plugin.php

Line 40 in ad98a82

private const FILE_PATTERNS = ['*.php', '*.yaml', '*.yml', '*.xml', '.env*', 'compose*.yml'];
