Minimum version of mariadb required

[anibalpacheco]

Check the minimum version needed of mariadb, (10.5.1 is ok)

MySql version 8.0.22 probably is not enough, because on main page load, an error like this will arise:

DatabaseError at /
(1055, "Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'ldsocial_ene_2021.core_edition.date_published' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by")

Nevertheless there is a way to bypass this, set sql_mode (sql runtime variable) to blank:
$ mysql -u root -p
mysql> SET GLOBAL sql_mode = '';
This is not recommended of course (further information: https://codeascraft.com/2013/03/19/the-perils-of-sql_mode/)
