Document SQLite's lack of BigInt primary key support

[mahendraHegde]

Describe the Bug

Choosing autoincrement bigInt as id actually creates integer auto increment.

To Reproduce

1. select sqlite driver
2. create a new collection with id as bigInt with auto increment
3. go back to field definition in UI and see, it will be reset to integer
