GraphQL playground Any type support

# Is there an existing issue for this?
No, I didn't see one.
- [x] I have searched the existing issues

# Current Behavior
The GraphQL playground doesn't support the `Any` type.
As a result, it shows a lot of warnings when people try to use Any type. I would like to add Any type support to the playground to improve the user experience.

However, I am not sure if this feature can be added on my side's Golang code, or it should be updated on the graphiql side.
If it could be done on my side, any hint that I can achieve this?
Thanks in advance.

# Expected Behavior
I hope the wavy red underline don't appear when the user is using `Any` type.
