GraphQL cleanup on rails backend and frontend

MRs:

Cleanup deprecated termination fields from work... (!189202 - merged)

Remove workspace termination fields from client... (!187507 - merged)

Description

Deletion time. We need to update the GraphQL types to reflect the removal of all the termination fields that we promised would be gone. We also need to update the frontend GraphQL schema to be compatible with the backend.

Acceptance Criteria

• Remove fields we promised to get rid off as part of the depreciation and removal process
• Update the frontend GraphQL client to use the new schema (types,mutations and/or queries)
• Exploratory testing to ensure no compatibility issues
