@deprecated fields in input type objects are not documented

[sahingoko]

Hi,
We are using @deprecated directive to mark field deprecation in our schema. And those are correctly documented with spectaql for object types other than input. With input objects, fields that are marked with the @deprecated directive is not documented at all, although schema is working fine and accepting those input fields. Is that intentional?

I just looked into this and found a few things:

• Official support for this in the GraphQL spec only recently just was approved/merged? Allow deprecation of input values (field args, directive args, input fields) graphql/graphql-spec#805 Allow deprecation of input values graphql/graphql-spec#525
• There is already a hidden option to the getIntrospectionQuery that supports this: introspection: Add missing support for deprecated input values graphql/graphql-js#2855 https://github.com/graphql/graphql-js/blob/main/src/utilities/getIntrospectionQuery.ts#L34

So, I'll be adding this in now as an option for you and others. Will try to have this out in the next hour or two.

@sahingoko this is now supported in 2.1.0 that I just published.

Because it's sort of a "breaking" change, it's not enabled by default. You'll need to set the introspection.inputValueDeprecation option to true in your config file, but then it should work.

@sahingoko does it work as expected for you?

@newhouse Yes, I just tested it in test environment and looks like it is working fine. Thanks again.
