Make GraphiQLProvider component's "inputValueDeprecation" property configurable

[xojc]

Feature description

Make the inputValueDeprecation property of the GraphiQLProvider component configurable.

Motivating example

Some graphql schemas, such as the one included in the Hasura GraphQL Engine, don't support an includeDeprecated argument at the IntrospectionQuery's fields' types' args level, and the graphql npm library support its configurable inclusion via the inputValueDeprecation, which is passed by the GraphiQLProvider component to the IntrospectionQuery retrieval method, so the ruru integration of the component should include configurability of the GraphiQLProvider's inputValueDeprecation property.
