UX improvement for teams list/get commands

[neel-astro]

• [x] I have checked that a similar feature request does not already exist.

✍️ Is your feature request related to a problem? Please describe. The current Teams get/list CLI command has a couple of shortcomings:

• There is no way to get the system-level roles for team/s
• The output of astro deployment team list and astro workspace team list list all the roles for that team irrespective of the resource/entity type it was called from i.e. astro workspace team list should ideally return back workspace level roles only. Currently, it would also return deployment & system-level roles. Ex:

🧩 Describe the solution you'd like

• astro team list command should display system-level roles
• astro team get command should display both system level role as well as individual resource level roles, i.e. for a given team list roles for all the defined workspace and deployments.
• astro deployment team list should display deployment level roles for that deployment
• astro workspace team list should display workspace level roles for that workspace
