Go 1.17 and MariaDB 10.6 are released (#1253)

* Go 1.17 and MariaDB 10.6 are released

* use `utf8mb4_unicode_ci` instead of `utf8_unicode_ci`

https://mariadb.com/kb/en/changes-improvements-in-mariadb-106/#character-sets

> The utf8 character set (and related collations) is now by default an alias for utf8mb3 rather than the other way around.
