✨ feat: add new post creation script and theme update script, remove git-protect.list and sync-upstream.sh

- Deleted `README-zh.md` and `README.md` as they are no longer needed.
- Removed `git-protect.list` to streamline the synchronization process.
- Introduced `new-post.ts` script for easier blog post creation with default metadata.
- Added `update-theme.ts` script to simplify theme updates from the upstream repository.
- Updated content configuration to handle optional updated dates correctly.
- Adjusted pin values in theme guide documents to allow a range from 0-99 instead of 1-99.
