chore: added new test cases for different plugins (#31068)

## Description
Added test cases for start with data flow by default. The test cases are
added for :
- `Postgres` : It should redirect to ds page with schema preview
- `Mysql` : It should redirect to ds page with schema preview
- `S3` : It should redirect to ds page with config and we can create
query on top of it
- `Airtable` : It should redirect to ds page with config and we can
create query on top of it
- `REST API` : It should redirect to action page and the action creation
is successful
