[BUG] Can't access item in array data type

[jonochang]

Describe the bug
When making the following query
SELECT keyName, tagSet[0], instanceId, instanceState, instanceType FROM awscc.ec2.instances
we get the following error

error:  You have an error in your stackql syntax; parser error: Code: INVALID_ARGUMENT
syntax error at position 25 near '['

To Reproduce

stackql exec "SELECT keyName, tagSet[0], instanceId, instanceState, instanceType FROM awscc.ec2.instances WHERE region = 'ap-southeast-2';"

Expected behavior
Expect to be able to access an item in the array type as defined in documentation here: https://awscc.stackql.io/providers/awscc/ec2/instances/

The aim is to extract the Name tag and value.

hey @jonochang the issue is with the aws provider in this case, the awscc.instances resource is a view projected from the aws provider, the aws provider is xml based and the tagSet field is not getting properly marshalled into an array, we will get this fixed and let you know
