Feature Request: Support `gql()` function in Python files

[Ariadne](https://ariadnegraphql.org/) is a GraphQL server implementation for Python that is gaining traction. It uses a Schema-first approach. It would be helpful if VSCode GraphQL could support syntax highlighting of inline SDL strings in Python code like it does for Javascript.

Instead of the `gql` template tag, in Python you would use the `gql()` function.

Note that Python supports both `'''hello world'''` and `"""hello world"""` for multi-line strings.

Example:

```py
from ariadne import gql

types = gql('''
type Query {
me: User
}

type User {
id: ID
name: String
}
''')
```
