Document the need of qualified names in snapshot.include.collection.list

When I use snapshot.include.collection.list to include a specific set of tables to be snapshotted, I get the message:

"WARN After applying the include/exclude list filters, no changes will be captured. Please check your configuration! (io.debezium.relational.RelationalDatabaseSchema)"

and no snapshot is taken.

My initial use case was with table.include.list. but it seems to also be an issue even if you don't specify any tables.

My usecase:

table.include.list: "table1, table2, table3"

snapshot.include.collection.list: "table1, table2"
