Function summarize

Summarizes an array of datapack deployment states into a single representative state.

The function uses the following logic to determine the summary state:

• If any deployment is 'InProgress', returns 'InProgress'.
• If no deployments are 'Pending':
  • If there are no 'Error' states, returns 'Success'.
  • If there are 'PartialSuccess' states, returns 'PartialSuccess'.
  • Otherwise, returns 'Error'.
• If none of the above conditions are met, returns 'Pending'.
