Update README.md Remove MYSQL_CHARSET & MYSQL_COLLATION attributes

These attributes are optional and only for use with MySQL 5.7 and earlier. They are also only available in the development version, not the release version. So I'll remove them from the documentation until I've done further testing.

MYSQL_CHARSET=utf8mb4
MYSQL_COLLATION=utf8mb4_unicode_ci

-### Troubleshooting Collation Issues
-If you encounter the error "Unknown collation: 'utf8mb4_0900_ai_ci'", this typically means you're connecting to an older MySQL version (5.7 or earlier) that doesn't support the newer collation. The server now automatically uses compatible settings, but you can override them:
-
-For MySQL 5.7 and earlier:
-```bash
-MYSQL_CHARSET=utf8mb4
-MYSQL_COLLATION=utf8mb4_unicode_ci
-```
-
-For very old MySQL versions (5.6 and earlier):
-```bash
-MYSQL_CHARSET=utf8
-MYSQL_COLLATION=utf8_unicode_ci
 ```
