Remote Schema to Database Array relationship returns invalid input syntax for type integer.

### Version Information

Server Version: v2.10.1
CLI Version (for CLI related issues):

### Environment
Cloud

### What is the current behavior?
I have got a custom Graphql server running in a separate server and I wanted to include a query from it to Hasura with the remote schema feature. I've created the remote schema and it is working well but I also needed to create an array relationship between the response in the remote schema query to a table in Postgres.

Currently, It is returning an error below.
`{
"errors": [
{
"extensions": {
"code": "data-exception",
"path": "$"
},
"message": "invalid input syntax for type integer: \"[\"36\", \"37\", \"38\", \"39\", \"40\", \"41\", \"42\", \"43\"]\""
}
]
}`

### What is the expected behavior?
To get the related entries from the database with the list of ids returned from the remote schema query response.

Start by reproducing the remote schema array relationship described in the issue, using the reported Hasura v2.10.1 Cloud setup and the returned list of integer IDs. Trace how the relationship value reaches the Postgres query and compare the generated input with the expected list semantics. Done means related database entries are returned without the integer input syntax error, with a regression test covering the case.
