Clean aks-as-mgmt.sh and Tiltfile

[nawazkh]

What type of PR is this?
/kind cleanup

What this PR does / why we need it:

• Updates default K8s version used in Tiltfile to v1.30.2
• Cleans up aks-as-mgmt.sh script by dropping unused ENV Vars.
• Delete peering code block in Tiltfile uses /bin/sh to process peering_names for PEERING_NAME in ${PEERING_NAMES} ... . /bin/sh fails with bad substitution when it encounters ${PEERING_NAME[@]}. Hence it has been replaced with ${PEERING_NAME} .
  • Note: ${PEERING_NAME[@]} is applicable when using /bin/bash to run the commands.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
