build: bump gql_client to partial-data fork

Pin the dependency to a revision that surfaces partial `data` on
errored responses via `GraphQLError::data()`. Lets callers consume
populated sibling fields when a per-field error propagates up to a
nullable ancestor — used by the upcoming up-front token validation
path to read the session even when `repositoryOverview` errors with
REPOSITORY_NOT_FOUND.
