* fix missing symlink to mysql binaries for MariaDB 11+
* update tested version of MariaDB 11.4 instead of 10.5
* add changelog fragment
* [CI] add way to trigger workflow manually
Useful in the case we don't modifiy any files in the paths: sections of the push event.
* add version check for mariadb < 10.4.6 without mariadb* binaries
* Use same concatenation method between functions to avoid future confusion
I didn't notice that db_dump and db_import were different, thus I introduced a bug with the initialization of the variable cmd. This commit fixes that.
