Add --format json flag to properly retrieve Project Item ID

[justinretzolk]

Description

While #32684 did add the correct jq filter in order to capture Project Item IDs when an item was added to the Project, the --format json flag is needed in order for the gh command to actually output JSON to parse. This PR adds that missing flag.
