The MYSQL_8_4 is only added to the documentation. Does it need to be added to somewhere else to be supported?

[sids-agravat]

MYSQL_8_4 is already supported. Ref b/383121405
I think this request name is confusing. It should be "Adding 8_4 version in documentation" instead as we already can create 8_4 instances through terraform
