nixos/nextcloud: temp fix for MariaDB >=10.6

Browse source 
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.

You seem to be using MariaDB at an unsupported version (i.e. at least 10.6)!
Please note that this isn't supported officially by Nextcloud. You can either
* Switch to `pkgs.mysql`
* Downgrade MariaDB to at least 10.5
* Work around Nextcloud's problems by specifying `innodb_read_only_compressed=0`
