The baseurl line includes the MariaDB version. So, you should change this line. If you want upgrade MariaDB 10.2 to MariaDB 10.5, the repository file should be like this;
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.5/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
