Breaking Change: Update useComputeApi param

[saadjutt01]

Current approach:

useComputeApi - Only relevant when the serverType is SASVIYA. If true the Compute API is used. If false the JES API is used. If null or undefined the Web approach is used. useComputeApi: boolean | null = null

Proposal:

To update param useComputeApi and it's usage, have it as an optional enum

enum ComputeApi {
  Compute = 'Compute',
  Jes = 'Jes',
  Web = 'Web'
}

Now that there is a breaking change in the 2025 Viya APIs (eg /sessions/{sessionId}/jobs we should implement this update

This will also allow us to be backwards compatible in the case of future changes in SAS
