Not compatible with Ecto 3.9

[drewble]

ecto_adapters_dynamodb 3.3.3 specifies a dependency on ecto_sql ~> 3.6 but I could not get it to work with ecto_sql 3.9.2 and ecto 3.9.4.

On ecto.migrate it would fail with this error

** (Protocol.UndefinedError) protocol Jason.Encoder not implemented for {:schema_migration, true} of type Tuple, Jason.Encoder protocol must always be explicitly implemented.

    (ecto 3.9.4) lib/ecto/repo/queryable.ex:19: Ecto.Repo.Queryable.all/3

Downgrading to ecto_sql 3.8.3 and ecto 3.8.4 resolved this issue. ecto_adapters_dynamodb should either resolve this issue with ecto_sql 3.9.4 or specify a dependency ecto_sql >= 3.6.0 and < 3.9.0.

Thanks @drewble, and sorry for the delay getting back to you. I was kind of passingly aware of this issue, but hadn't really dug into it to check exactly what version limitations need to be imposed. I'll add those when I got a chance.
