Improving SQL Server setup documentation when using custom types

[ilianiliev-redis]

Note

Low Risk
Documentation-only changes with no runtime or security code impact.

Overview
Adds section 5 to the SQL Server RDI prep guide for tables that use user-defined types, documenting that the Debezium user needs GRANT REFERENCES ON TYPE::<schema>.<type-name> and showing the misleading primary-key error you can see without that grant.

Also fixes the missing newline at end of file on the schema-change note at the bottom of the doc.
