nixos/nextcloud: temp fix for MariaDB >=10.6

The MariaDB version 10.6 doesn't seem supported with current Nextcloud versions and the test fails with the following error[1]: nextcloud # [ 14.950034] nextcloud-setup-start[1001]: Error while trying to initialise the database: An exception occurred while executing a query: SQLSTATE[HY000]: General error: 4047 InnoDB refuses to write tables with ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE. According to a support-thread in upstream's Discourse[2] this is because of a missing support so far. Considering that we haven't received any bugreports so far - even though the issue already exists on master - and the workaround[3] appears to work fine, an evaluation warning for administrators should be sufficient.
