Backend: Add `type` and `description` to InputType in GQL

Summary

Currently, type and description are not available via the API and those fields are needed so that they can be displayed in the components tab (noted in #426870 (closed))

Proposal

Add type and description to InputType so it can be access via the fronted in components tab.

Confirm purpose and User Reception (how does this benefit the user?)

Show type and description in components tab.

• Is there an example response showing the data structure that should be returned (new endpoints only)?
• What permissions should be used?
• Is this EE or CE?
