blogs: mysql vs mariadb (update) - json (#456)

Comparing MariaDB json functions to MySQL
* https://mariadb.com/kb/en/json-functions/
* https://dev.mysql.com/doc/refman/9.1/en/json-function-reference.html

There are 4 functions that MariaDB doesn't have that MySQL has being
JSON_STORAGE_FREE(), JSON_STORAGE_SIZE(), both unimportant due
to MariaDB storing as text, and:
* JSON_SCHEMA_VALIDATION_REPORT
* MEMBER OF().

A look at what MariaDB functions exist that MySQL does not have is:
* JSON_ARRAYAGG
* JSON_COMPACT
* JSON_DETAILED
* JSON_EQUALS
* JSON_EXISTS
* JSON_KEY_VALUE
* JSON_NORMALIZE
* JSON_OBJECT_FILTER_KEYS
* JSON_OBJECT_TO_ARRAY
* JSON_OBJECTAGG

Its a bit hard to argue MariaDB JSON functionality is behind MySQL
based on this concrete comparison of features.
