Ruru: make inputValueDeprecation/schemaDescription configurable for older schemas

### Feature description

Currently we hardcode these to be enabled:

https://github.com/graphile/crystal/blob/3ca966185b0029e638cfecadeca8d5cc16e1cc34/grafast/ruru-components/src/ruru.tsx#L73-L74

We should either add feature discovery, or make it so someone using `ruru` on the command line can disable these features for servers that don't implement the latest draft of the GraphQL spec, such as Hasura.

### Motivating example

Hasura produces `'args' has no argument named 'includeDeprecated'`

### Breaking changes

None
