Refactor action example imports and add example files

Moved action example data to dedicated 'examples.ts' files for each action category (extends, file, go-cqhttp, group, msg, system, user). Updated all action classes to import and use the new example modules, improving code organization and maintainability. Also added missing actionTags and actionDescription where appropriate.
