[Known Issue] MySql Support for CREATE/UPDATE actions on view - Difference in Config files

https://github.com/Azure/data-api-builder/pull/891 implements support for mutations on views for MsSql. Among CRUD operations, only read and delete can be executed on MySql views as of now and thus there are differences in config files for MsSql and MySql (highlighted here: https://github.com/Azure/data-api-builder/pull/891#discussion_r999834468. Has to be taken care of when other operations are supported for MySql.
