(GH-915, SCHEMA) Loosen type name pattern

Prior to this change, the pattern for fully qualified type names
specified that a type name required an owner and supported up to
two namespace segments, separated by a period (`.`).

This change:

- Loosens the pattern by allowing a third segment for subareas.
- Updates the in-schema documentation to reflect the change.
- Fixes #915
