MDEV-25106 Deprecation warning for innodb_checksum_algorithm=none,innodb,...

Browse Source 
MDEV-25105 (commit 7a4fbb55b0)
in MariaDB 10.6 will refuse the innodb_checksum_algorithm
values none, innodb, strict_none, strict_innodb.

We will issue a deprecation warning if innodb_checksum_algorithm
is set to any of these non-default unsafe values.

innodb_checksum_algorithm=crc32 was made the default in
MySQL 5.7 and MariaDB Server 10.2, and given that older versions
of the server have reached their end of life, there is no valid
reason to use anything else than innodb_checksum_algorithm=crc32
or innodb_checksum_algorithm=strict_crc32 in MariaDB 10.3.
