utils: Changes to enable re running commands with copilot

[motm32]

This PR includes a couple of changes:

1. Edits to copilot prompts to extract subscription and activity log child items
2. Edits to copilot user input to match up the picks based on label and subscription instead of the entire item (this makes the command run much faster)
3. Wrapper to executeCommand so we can pass in additional context
4. Add a run generic prompt step which preforms similarly to runQuickPickWizard but doesn't require the step to be a quick pick step.

Some of these changes are used in RG and others in the ACA extension I will link them both once they are up.
