JobsetInputs: update schema to align with the API

`PUT /jobsets/{project-id}/{jobset-id}` expects a JSON object `inputs` which
maps a name to a name, a type, a value, and a boolean that enables emailing
responsible parties. However, `GET /jobsets/{project-id}/{jobset-id}` responds
with an object that doesn't contain a value, but does contain a jobsetinputalts
(which is old and should be unused).

This commit aligns the two by removing the old and unused `jobsetinputalts` from
the response and replaces it with `value`.
