Fix array type missing from query schema selector (#12772)

* Tidy MongoDB aggregation pipeline view

* Remove unused code

* WIP

* Add bindings for bindings drawer

* Is not external table if it's a query

* Add QueryArrayFetch

* Bug fix

* JavaScript is the worst

* refactor

* Add array label to query schema

* Remove console log

* type fix

* Don't include Array in SchemaTypeOptions, but show label

* Fix bindings

* refactor

* Rename isObject to hasSchema

* WIP

* Typing WIP

* Type not Types

* Unused import

* type fix

* Handle json array subtype

* Support queryarray datasource type

* refactor

* yarn lock

* update account portal
