Enabled the Plugin Update Checker to allow automatic updates from the GitHub repository.
Changes:
- Uncommented and enabled plugin-update-checker library
- Configured to check 'main' branch for updates
- Uses YahnisElsts Plugin Update Checker v5.6
- Monitors https://github.com/JRG-code/Geo-and-IP-block for releases
How it works:
- WordPress will check GitHub for new versions
- When a new version is pushed to 'main' branch, it appears in WP admin
- Users can update directly from Plugins page
- No need to manually download/upload plugin files
This resolves automatic update issues mentioned by the user.
