将 MySQL 的表创建脚本 name 列字符集改为 utf8mb4_bin 以使其对大小写敏感

Fixes halo-dev#4372

**how to test it?**
使用 docker 运行 MySQL

# mariadb 同样将镜像改为 mariadb 后执行相同步骤
docker run --name mysql-test -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=halo -p 3306:3306 --rm -d mysql:latest

insert into extensions(name,data,version) values('A', 'A', 0)
```
