[schema-ast] sort parameter ignored

### Which packages are impacted by your issue?

schema-ast plugin

### Describe the bug

With the `schema-ast` plugin, the `sort` option is ignored and the output is sorted every time.
I'm trying to dump my schema composed of multiple `.graphql` files but don't want my graphql `input` properties sorted as generated code depends on this order.

### Your Example Website or App

Personnal repo

### Steps to Reproduce the Bug or Issue

Create a simple type and generate the AST from it while setting `sort: false` as argument.

```yaml
./path/schema.graphql:
plugins:
- "schema-ast"
config:
sort: false
```

### Expected behavior

When using `sort: false` the properties of generate AST shouldn't be sorted.
