Subject: [PATCH] Declare property defaults so unset optional properties have a
 value

Several resource types documented a default in prose without declaring it, and
the ones that did declare a default had no effect because Radius never
materialized them. Declare the missing keys so they take effect alongside
radius-project/radius schema defaulting.

Added: size on redisCaches and postgreSqlDatabases, version and database on
mySqlDatabases, and database on postgreSqlDatabases. neo4jDatabases is left
alone because its documented default is the resource name, which a static
default cannot express.

The mySqlDatabases version default is 8.4, which is what the AWS Terraform and
Kubernetes Bicep recipes already fall back to when version is unset. The Azure
pack maps everything except 5.7 to 8.0.21, so it deploys the same image either
way and only AWS and Kubernetes would notice a different value. Declaring 8.0
here would have silently downgraded them, and a running RDS instance rejects a
major version downgrade outright.

Related to radius-project/radius#12532
